Has any one else noticed an issue where the sound will be ahead of any video by about half a second? The problem becomes worse when using bluetooth audio. Normally with bluetooth audio the sound lags behind video, but on this phone, with or without bluetooth audio, the sound is always ahead of video.
I notice this most with pocket cast.

Sounds like you have PowerSave on.
Here is why I say this... I can watch videos with no lag. However I don't know about Bluetooth lagging, bc i dont use BT. I know the videos are not lagging, because I read lips everyday since my hearing is quite dull. I can hear the voice and see the word at the same time. Likely, what is happening, is that your internet connection (LTE,WiFi, or 3G if you have good 3G), is downloading and buffering the audio which gets processed via the network interface (no task offloading to the CPU on phones). Now, your video is being processed via the GPU/CPU. So either your voltages are too low, or your frequencies are too low, or you have powersave on which limits you to 1.1Ghz. Perhaps even too much cached data. Flash a new ROM, and then flash ElementalX kernel with 450Mhz GPU, and use 'run hot' as your thermal steps (youll see these options during your flash so dont worry if you dont know what im talking about).
Yes, i have noticed Netflix video sync issues when power save is enabled. It works fine when disabled...

I am thinking of buying bluetooth headphones because my wires constantly tangling and eventually ripping or breaking is really pissing me off
so i what i want to know is:
How good is the sound quality (this matters to an extent)
does it cut out a lot (if yes is there a fix)
how much does it affect the g1 battery life
thanks i advance

I don't know how much of it is introduced by the MP3 decoding software, the A2DP link, and my A2DP headset, but I do notice a slightly higher noise floor listening to MP3s on G1 as compared to on my computer. It is mainly noticeable during the period between when the headset initializes a stream and when audio actually begins to play. Quiet portions of songs and musical pieces with high dynamic range (classical, mainly) also will suffer disproportionately. If you don't listen to music with high dynamic ranges or significant quiet parts, then the noise floor will likely be imperceptible.
On drop outs: Since BT operates in the ISM frequency, if you live/work in a place with heavy WiFi usage (an apartment complex, an office park) you may notice frequent drop out. In extremely WiFi noisy areas, it can be at the point where it's unusable. The other reason for drop outs (more uncommon) results from the phone hitting the limit of its processing power and being unable to decode the MP3 in realtime. You will notice that while using A2DP music playback, the phone will act more sluggishly, especially for realtime applications like games. I encode my MP3s as LAME -V0, and at this setting the G1 requires 8% CPU to decode. However, playback of the same material over A2DP increases CPU usage to ~30%. The reason for the additional 22% is due to re-encoding to SBC for A2DP. I recommend not running a Rosie/Sense UI with A2DP.
Battery life will also take a nice hit too. In addition to that extra 22% CPU time (meaning more battery consumption), the phone will have to run its BT radio nonstop. I haven't run any battery life comparisons myself, but expect the usable battery life to drop considerably with A2DP playback as opposed to using the wired headset.

I dont live in a wifi heavy area (or any where near one) and dont use the phone for much except browsing while listening to music i guess ill have to go to a cyan rom now(ill just use a hero theme ) Thanks for the great answer
I've had lots of issues with different stereo bt headphones, I think the problem is mostly on the headphones side. Flaky playback, audio actually changes speeds while listening to songs, audio cuts out periodically, can't forward to rev to other songs. I've had all these issues and more on my G1, and a Samsung P2 and P3, so I'm blaming the headsets.

I thought I was going crazy when I first heard this, but apparently its a problem with a lot of a2dp setups. In a way pitch changes are more irritating than drop outs since atleast most of the time it's pretty clear when you have a drop out.
I have an LB HBS 200 headset (I think that's the name). Talking quality is the same as any other bluetooth headset I have ever owned. Kinda choppy. However, that is not the case for the music part. The music sounds great and I have never had trouble with it. Best off, it's only $25 at Fry's Electronics! The next closest one I saw was a motorola for $50. You should look into it. I highly recommend it.
I have noticed that when I use Pandora on Froyo the audio quality is significantly worse than it was on stock 2.1 or cyanogenmod 5.0.7.1.
I am aware of the High and Normal settings in the preferences however it does not help.
Under 2.1 (stock and cyan) Normal would sound alright and High would sound fantastic.
Under 2.2 (froyo) High sounds bad and normal is horrible.
Has anyone else noticed the sound quality drop in pandora moving to Froyo?
This is independent of the song being streamed and is very noticeable when using good headphones.
Are you using the stock 2.2 kernel or one with the audioboost patch?
I have tried using multiple kernels including stock, cyan 2.6.34 and ravens avs 2.6.33.4 kernels. Does not effect the problem at all.
I'm running Paul's pre-root (including 4.06 radio and kernel that came with it) and sounds great to me, same as before (CM 5.0.6+oc/uv+audio mod+desire cam). In fact I'm not sure if I've reset it to stay on High with 3g yet since I updated. (Tmo USA N1 if it makes a difference ).
Wish I could give helpful input other than its possible. I know I wiped everything I could and flashed it over CM.
Running Paul's root with IntersectRaven's .34 kernel and Pandora sounds as good as it did with his kernel on CM5.0.6.
Haven't noticed a difference.

same here.
Hmmm, I will look into this more and report back if I find anything.
Thanks for the help guys.
I as well noticed this problem, tried resting/full wipe, restarting, toggling settings to no results. Terrible audio quality even in high. Other sounds are not affected it seems. Running kernel that the update brought.
Am I the only that has actually plugged the phone into an fm transmitter to use with my car stereo? Of course i am, you kids all have your bluetooth radios and your xms and syriusnessess. When using Pandora, the bass is much much louder in froyo than it was in all previous roms. Kernel with modded sound or not, the bass is big. So, yes, the sound is very different from what it used to be. Mids are too high and highs are meh... nonexistent. It doesn't sound bad on the phone or through earbuds, but unless you like rap, you probably won't like the sound coming through your car. But, I don't think that's anything some decent equilizer software can't fix. Personally, I think the sound is an improvement despite the focus on the lower end of the spectrum. In previous versions, it was to light and airy with no lowend.

I am on Froyo, and I notice it.
Also, I notice that songs frequently stop playing in the middle or near the end, and then Pandora seems to fail to recover and skips to the next song. Does that happen for you?

The same thing happens to me while on 3G, and happens mostly while moving. If I stay still, I can play continuously with no problems. But while walking or driving, I usually can't finish a song before it skips. This also happens on any other internet radio app, like DroidLive and Slacker.

Yes, I've noted that, as well as fairly frequent brief pauses that do resume and continue to play the current song without skipping to the next. (The combination of my ears and my stereo system are not sufficiently discriminating for me to detect any difference in the audio quality, though.)
I've noticed that I can't control the next song, play/pause with the Bluetooth controls anymore. I hit next to skip a song and my music player starts playing while Pandora is still playing.
I use Pandora often in my car and I also can confirm the audio quality is now horrible for me on Froyo.
If I nandroid back to my CM backup it sounds fine but under Froyo it sounds horrible.
I also have noticed a decrease in audio quality, but that might be due to changing ROMs from CM to Stock Froyo leak... (don't really know how the builds differer audio wise)
@ maxawesome
I'm glad I'm not the only one experiencing problems with Pandora. Often my music just stops... sometimes it won't continue streaming either... It worked flawlessly with CM 5.0.6 (though i only use it in my car...)
I am also confirming that after the Paul's Froyo zip update the audio quality has decreased dramatically. It almost seems like the sample rate is much lower affecting mostly higher frequency sounds like voice or instruments that produce higher frequencies. The bass sounds ok, but there is alway a small hiss noticable.
Also, when my screen turns off while Pandora is playing I noticed audio drop out over the BT connection. When I force the screen on this does not seem to occur.
Had the desire rom on it before and audio was stunning, almost CD quality.
Hope someone finds a fix or workaround soon.

Agreed, happy to know I am not alone with the issue. For now I have reverted to Cyan 5.0.7.1.
i don't know about pandora, but the stock music app sounds a ton better to me, both through headphones and through my car speakers (using the POS 3.5mm to tape adapter, lol)
The other day I plugged my N1 to my car and noticed the quality was a lot worse. At first I didn't think much about it or even the fact that it was because of Froyo until I came upon this thread. But yeah, the quality is a lot worse now. I am thinking Pandora needs a update.
I am running a bell HTC one rooted w twrp installed.
I have noticed that YouTube and other internet video either on WiFi or data has quite a bit of delay to the video vs the audio.
It's Very distracting as the audio is prob 1/2 sec ahead of the video.
Beats on or off doesn't change anything
power saver on and off doesn't matter either
else have this problem.
Audio / Video sync.

I have this issue as well... it seems to come from using Bluetooth. Once you view a video with a Bluetooth device attached the audio will be a half second ahead. This will remain the case until you let it play out of the speakers... if you immediately plug in a headset it will continue with the out of sync video. Once it plays from the speakers it'll line up again, then you can plug in headphones and it'll still line up. I cannot believe I have read 50+ reviews of this device and not a single mention of this issue. This is a deal breaker for me so now I don't know if I should return it.
even after i disconnect bluetooth the audio is still out of sync. I havent tried turning off bluetooth all together though.
Couple of questions. So far, I absolutely love my Nexus 6, however I have a couple of questions/quibbles.
Firstly, the volume on this thing. How quiet/loud is it supposed to be? When it's in the low end scales it's very, very quiet, middle is passable, loud is good, but is the quieter levels supposed to be so quiet? I compared it to an iPad 3 and that speaker is louder overall, I assumed the Nexus 6 would be louder everywhere (highest level very loud, lower end quiet but loud enough to hear) than the 3 year old iPad?
Secondly, the microphone. I'm a little confused by it. In videos I've recorded the mic volume is good enough, but using WhatsApp I things I've recorded sound quiet, at least compared to iPhone recordings (friends have iPhone's), and then it's slightly better in "Easy Voice Recorder", unless I whack up the gain on it.
What's the deal? Or are all Nexus 6's like this?
Also, what's the battery life supposed to be like?
I'm on fairly low brightness, auto adaptive brightness or whatever is off. Unplugged at 8am, its been 12 hours. On 22%. Used the phone 20mins browsing internet going to work, stuck in my drawer till 1pm with occasional checks, 20mins used it playing Jetpack Joyride/internet browsing, home from about 4, been playing music on and off through Google Play, couple of YouTube videos, browsing the web etc, nothing too intensive, and I'm on 22%. Does that sound right?
Anybody?
Yeah, you my friend have had the 2 most common problems with the nexus which come standard with the device. For battery, you need to get a kernel with intelliplug and enable it over the stock mp decision. You can even overclock with battery life better than stock. (Like me) For audio, try to find a kernel with faux sound, download viper4android for music, and change some values around in mixer.paths.xml. You need to be rooted with a recovery first before any of this. The problem with video recording is that it is also recorded in mono instead of stereo. Weird but I have been able to fix all of these problems now. If you need any help, quote me. Please give a thanks if I solved your issues.
Thanks for reply.
So what I've described aren't necessarily problems as such, they're just standard on the phone? The battery is okay it's just not amazing. I'm on 50% now, unplugged 14 hours ago, used it for a bit of internet browsing, texting. Was on standby for about 9 hours and was on a call this morning for about half an hour and then I've done some more browsing and texting today. I'm also on adaptive brightness.
Does this sound right?
And the microphone, if I use it on WhatsApp, people keep saying it sounds clear, it's just very low. But again, if I record a video it comes through fine.
Is this normal to Nexus 6's or is there something wrong with my mic?
really low here to in whatsapp, can somone please help us? i do not want to have to send my phone back!

Same issue here. The mic volume in all IM apps like whatsapp, Skype and etc are very very low. However the voice in the recorded video is OK.

yep thats what im getting....anyone else?
Yeah that's really annoying. The problem is, that the N6 use the mic at the bottom on the rear site. If want to make a videochat with the frontcam it's really stupid.
Normally it use the rear mic to reduce background noise. But this seems to work only with telephone calls?
Did anyone ever solve this problem?
Would a Bluetooth headset be a "fix"?

It is default mechanism.
You can install 3rd party Sound recording app and forward recordings to them.
I'm using an AT&T variant in a Chevy 2015 Equinox. The phone operates fine with calls but stutters and skips with streaming audio. Any app I use it does the same thing; Poweramp, Google Music, Pandora, etc. My wife's iPhone 6 Plus has no issues whatsoever. Is this a phone issue, an AT&T software issue or car issue? Anyone experience anything like this and can give me some direction? TIA
I had something like that happen before. Doesn't happen much anymore. I wasn't streaming though. Listening to podcast I downloaded. It would play fine for a while but then start to stutter. Would work fine after I woke up the phone so assume it had something to do with the processor dropping down too low like it was trying to go to sleep or just the use the low power cores maybe. Just a guess. Doesn't happen anymore though. I'm on t mobile.

This is a widespread issue with Bluetooth on Android (since about KitKat, possibly earlier) that spans just about every possible combination of hardware and software. It is exactly like you said -- the phone's CPU is too slow to keep up with Bluetooth audio decoding and streaming when the screen is asleep. The CPU governor is too aggressive on saving every last microwatt of battery life, and would rather your experience suffer instead.
The issue is very well-documented, but Google refuses to fix it. See here for hundreds of complaints spanning every major manufacturer and just about every imaginable Bluetooth headphones, speakers, headset, earbuds, etc. etc.:
https://code.google.com/p/android/issues/detail?id=95294
its an easy fix, just download kernel adiutor, set the minimum to 500 and see. I personally set the min and max of little cpu to 900 and big to 1200mhz.
