Bluetooth sounds bad

Hey all,
I have Froyo 2.2 on my N1...anyone know why my bluetooth headset crackles and is really fuzzy sounding? Sounds like they are underwater sometime...I even tried a new bluetooth headset with same problem...any ideas? Thanks.

which FroYo ROM, and which kernel.

mine does the exact same, its not just you its probably a froyo issue.

ok so i was bored and did some tests, it seems it only happens to me when trying to send audio via bluetooth when playing a flash video, reg music and videos are no problem.

I also have same problem, but on CM 5.0.X (Android 2.1). I tried Motorola S9-HD (stereo) and Nokia HS-56W (mono). Every time connect the headset and the phone is very close (20-30 cm), the sound is fine, but as soon as the phone is to push further, the sound is choppy and stutters. And this happens on any headset.

is WiFi on or off?
WiFi and bluetooth operate on same frequency band and can cause issues.

i have wi-fi on and bluetooth on.

switch WiFi off and try.

I switched off Wi-Fi and connect Motorola S9-HD and it really workes. A will try today use more and write late about it.

Same problem here with Froyo.
I turned Wifi off and the sound problems went away.
I think is a hardware problem or design problem because I used to use the same headset (Motorola H-710) with an iPhone and never had this problem even with Wifi switched on.
Would be any way to get rid of this problem?, it really bothers me to turn off the Wifi every time I get a phone call.
Thanks

its a problem with flash, not bluetooth, adobe should fix it soon

Thank you for the suggestion I will be sure to try that tomorrow!
I have kernal 2.6.32.9-27220-g328f560 android build apa26 #1
Build number is frf50
I hear this is a test version of Froyo anyway...I don't think the real Froyo has been released yet? So maybe it will be fixed...thank you.

After two days of tests, with switched off Wi-Fi, it turned out that the problem does not disappear completely. Correctly identify the reason for failed. Since stuttering occurred on different songs (that is, perhaps, that stuttering is dependent on the bitrate), I sometimes felt that the problem with lowering the frequency of the processor in sleep mode, and it is not enough to encode mp3 and transfer data via Bluetooth.

Still bad with OTA
I got the froyo OTA for my stock N1 yesterday morning.
I can confirm that the distorted sound is present on the phone application only when wifi is turned on and you are using bluetooth. At first I thought it was only when wifi was on but not connected but it appears that you can get the distortion on a phone call whenever wifi is turned on.
All entertainment application seem to work fine with my A2DP bluetooth. Again it only seems to be bluetooth phone calls and wifi turned on. Believe me this is bad enough. This didn't happen on 2.1 and if it weren't so much hassle I'd probably go back.
Hopefully someone will come up with a workaround that will allow bluetooth calls and wifi turned on at the same time. Gees, if it weren't so basic

This just drives me nuts that Google makes major changes to parts of the OS, then doesn't think to actually TEST everything they changed. This would easily been detected if they actually tried it out. Duh.

I have the FRF91 update and all the blutooth distortions are GONE.

I updated from stock via the OTA to FRF91 and thats actually when the distortions showed up on mine? Well its good to know that there is hope but now I am wondering what possibly may be different between mine and yours?
Can anyone else tell us how their bluetooth is doing on FRF91?

Does anyone think a froyo factory data reset is worth trying?

[Q] bluetooth with car stereo problems, you guessed it

Okay, so lots of people have problems with their bluetooth. I am too. I have a JVC KW-XR810 car stereo and the bluetooth keeps shutting down on one or the other. My questions are:
Does anyone else have this stereo and problem? If so, whats the situation?
Is there a ROM that works flawlessly (or close to) with the bluetooth?
Its odd though, that my headset works perfectly and I didn't have many problems with another stereo I've used. Makes me wonder if its the stereo or the phone. Still, many others have bluetooth problems with this phone...
Thanks for any responses.
Stock Froyo
Rooted
One click lag fix

My last 3 phones (including this one) have all worked flawlessly with my Sony MEX-BT3700 head unit. Phone calls, BT dialing, streaming music, all work perfectly.

Yep, same here - AT&T replaced my Captivate under warranty about 2 or 3 weeks ago due to the random shut-down issue. Took the new one home, installed Froyo, and rooted it. Everything works well, except lately I've been getting frequent bluetooth disconnects from my car stereo (Pioneer AVIC-X920BT).
The usual pattern seems to be it's good for about one call, and then shortly after ending that call, I notice that they are no longer connected. I usually turn off BT on the phone (seems to take a while to terminate) and then turn it back on, but it will usually only be good for a single call. It's been frustrating, and I'm leaning toward the problem being on the phone side, since that's where there have been recent changes.

Must be a problem with Stock Froyo. Glad I'm not using it.

I've had this issue with certain roms I was running. I have a Kenwood KDC-X993. So far on CM7 it stayed connected.

i have the same (or similar) problem with my OEM headunit on a VW Golf. BT randomly disconnects but my music (pandora) still plays through the BT stereo, unless I stop it. Then its completely disconnected and I'll have to reconnect the phone to the car.
annoying but I just deal with it.

I'm running Paragon 6 and have a Dual head unit. I haven't had any disconnect issues, my problem is the crappy Pandora app.

Same here, I have a Parrot mki system in my car, but I found a workaround that I hope works for you too:
Unpair with the device, and when you re-pair it, when it asks you to synchronize contacts, do not let it. It will bug you every time it connects, but just ignore the requests.
I haven't had a single disconnect since doing this weeks ago.

I've read about the contacts request from other users but it doesn't happen with mine. Another thing, when I lose the connection and I turn off bt one the phone out shuts off. Completely. Pushing the power button does nothing. Holding the volume up and power buttons together for a few seconds seems to restart it but theres no animation. Just the lock screen, media scanner, etc. Maybe its restarting on its own and the button pushing has nothing to do with it. Also, I listened to my bt headset for hours last night with no probs at alI. Idk. Is bt different for head units? I thought it all used the same protocals.
So it seems that its not my head unit, but the phone. Are there any good solutions for us?

My head unit never asks to download contacts. Could it be that some do because they store that info in order to identify and announce incoming calls? That would mean there's more going on than just a simple BT connection.

Yeah. One post I read said something about it using a data connection the hu for contacts. I have no idea what he was talking about though.

My head unit have the ability to sync contacts. When I first paired it, the phone asks me for permission and there's a check box to always allow.

The only purpose I can see for this is if the head unit has an integrated nav system. That would allow you to bring up a contact as a nav target independent of the phone.

Okay, gettinging back to my original questions. So far we've established that this is endemic to the captivate, mostly. There have been two replies saying that cm7 and paragon 6 have stable bt connections with head units. I read in another post that axura works as well. This is so frustrating that I'm just about willng to learn how to flash this thing.

We have? My first post says I have zero issues with this on my head unit with my phone on Eclair, Froyo and now Andromeda. If it is a phone issue mine is not suffering from it. Sounds more like it has something to do with head units that store contact data. Mine apparently doesn't.

Hmmm.
Yet in your second post you posited that it must be a Froyo issue.
Regardless of whether it is the phone or OS, a lot of Captivate owners seem to have bt issues of one kind or another with various devices. Maybe this is just a bt issue in general that everyone deals with (not just Captivate owners) and I'm just being sensitive because I haven't had much bt exposure.
Any help is appreciated here. I'm just looking for suggestions on what to do short of buying a new phone or head unit. It would be great if other users experiencing this problem would benefit from the discussion as well.
So far it appears that flashing a different ROM may be a solution but which one? Is there any way to change only the bt stack?

Sorry if that sounded short, but I'm REALLY frustrated with this.
My hu will store contacts as most do these days, but it doesn't ask for them. I don't think the problem is related to the contacts. I guess its just a random incompatibility thing.

I said it "might" be a problem with stock Froyo. I didn't see it the 3 days I was running it and my current ROM is Froyo-based and working without issue. The only other variable I can see is that others posting problems have reported having to deny access to contacts, something my head unit never asks for, in order to get it to work. That would appear to indicate the difference is in the head units and not the phones, but unless I could connect to one of these other head units to verify, I'm only guessing. Sorry.

i notice that if I toggle the bluetooth on my phone right before connecting it to my car, it works flawlessly

Installed a Kenwood X994 and had all kinds of issues with BT. Worked for awhile but would never auto connect. Only vehicle and area where I had BT issues. I realized it was due to the downloading of contacts at every connect. sometimes it would download than immediately disconnect. frustrating. Was on serendipity, Tried a native Cappy ROM, Cognition and now Phoenix..
The unit has the Parrot system in it so it should be ok. Finally decided to update the Firmware on the HU. So far so good. I like the contact download so I don't need to use the phone at all to make a call. Receiving calls is no problem.
Will test further tomorrow.
BTW I have a BT Garmin mounted in the truck and used it before getting the head unit. no problems connecting. The only issue with that was a delay between pressing the call button and the call being made. Hanging up was an issue as well.

Bluetooth Issue

So I paired the One with my QED uPlay at home and I'm having issues. The phone has to literally be 30cm away from the receiver or the audio will start getting distorted until it eventually cuts off. I have two uPlays, issue exists on both so its not tbe receiver. Also my iPhone 4s has no issues either. I was hoping the One had better audio than the iPhone since it has aptx, but its quite the opposite. Has anyone tried bluetooth music streaming? Is it just a faulty phone?

Bluetooth and Wi-Fi both use the 2.4GHz channel. Asus had issues with the Prime because of its all-aluminum design where they had to greatly amplify the Wi-Fi signal and use diversity antennas to get through it. HTC uses the latter on the One. When used together, the Wi-Fi signal can overpower and interfere with the BT signal. Try turning off Wi-Fi and see if your connection quality changes. You're the first one to mention a BT issue so it could be unique to your device. Time will tell.

I have had a problem with bt connecting to my car (audi a1) I can hear the call but the other end cannot hear me. Going to delete connection and try again tomorrow.

Thanks for the replies. I switched off WIFI, re-paired the device and bluetooth started working perfectly, so it makes sense it was interference. Strange thing is I turned WIFI back on and bluetooth was still working fine. I'll do further tests in my car tomorrow see how it goes. If I'm not convinced I'll just get the phone replaced.

I have also had issues with bluetooth paired to my hands free car kit. Issues have surfaced when streaming music and also when making audio calls via bluetooth.

The One X had a similar issue:
http://forum.xda-developers.com/showthread.php?t=1688538
It could be that when I was first trying the WIFI antenna was stuck on high power, which caused the interference, but when I reset the WIFI it reduced its power and no longer interfered with the BT. I have changed the WIFI at home to run at 5 GHZ, but work still runs on 2.4.

I am running 1.28.401.7. How did you update to the latest ROM? I don't want to unlock my bootloader in case I need to return it.
Did you used to have the same exact issue in the previous ROM?

Apparently 1.29.709.4 has been officially released in Taiwan by HTC, so it shouldn't be long before the update arrives to the rest of us (hopefully).

got the same issue...some times I got no lags in audio streaming, but sometimes they are there...until it (maybe) will be fixed I'm using a widget, my cousin has coded for me yesterday . Quite simple solution. If I press the button, wifi turns off and bt turns on...works fine for me, so far

[Q] Ringtone coming through PC

Hello there,
Yesterday while at work, I received a call. My phone wasn't connected to the computer via usb or bluetooth, and wasn't on the same wifi network. There was a ringtone coming through my PC speakers! It was weird. It was different ringtone that my phone has. I tried calling my device three times afterward, and it still came through. Phone not connected in any way, and a different ringtone came through the PC speakers!
I cannot recreate this issue today I wanted to know if anyone else came across this? I am using a stock rooted ROM. Sense 6, the newest update out now.
I just find it odd. It's kinda cool though. If it is a feature, I would like to enable it.
Any thoughts?

Bluetooth issue

This issue isn't new to the N6.. I had it with the N4 and N5 as well, but haven't had it addressed so far.
I've got 3 devices paired with my phone, a bluetooth ear piece for calls, my car audio system, and a sound bar. Each time I turn BT on to connect to a device different from the last one, I have to go into settings and touch the device I want to connect. It won't automatically connect to anything, unless it's the same device it was last connected to.
Is this normal behavior? If not, has anyone gotten it to work properly?

So, is this too uninteresting a topic, am I the only one experiencing it, or does it just not bother anyone else?
