I have a google car dock for my nexus one and I hook the audio through the car stereo with a 3.5mm audio cable. When it is plugged into the dock the sound is very low and the quality is terrible. If I just pull it out of the dock everything is back to normal -- this happens with all apps.
What do I have to do in order to prevent the phone from doing this while docked?
you have the exact same setup as i do and ive seen this as well, i think there is something that makes the audio play at a different volume specifically for when it is docked for some reason. im on cm6.1.1 and it seems a little better because i believe they tweaked something with it, i saw a checkin on cmsrc on twitter that modified some line with dock volume.
what ive found is if i set the media volume to about 5/8 or 7/8 then dock it the volume will make its "dock adjustment" and its up to where my car volume is from there, usually a little less distortion if the phones volume is a little lower than max. from there if i forget to set the media volume i will use the preamp slider in the poweramp music players equalizer to adjust.
i just wish the volume wouldnt change at all and the volume button on the side of the dock would change the media volume :\
side note: have you noticed that the voice search when docked doesnt pick up your voice very well? almost like the noise canceling mic is cancelling you out or something and other times it can pick up your voice great?
Actually the sound volume was solved by some user that re-compiled libaudio with the code that lowers the sound by 10db commented out. The problem I have is that the sound quality is so poor that it seems to be mono without bass.
It turns out that the crappy audio quality comes from Bluetooth being on. When I disable Bluetooth in car mode, everything is great. Unfortunately I can't figure how to make it disabled by default so I have to disable it everytime.

I have the problem that, when the music ist very quietly I hear a loud noise in my earphones. When I pause teh music i hear it loud. When the player shuts down the noise is away.
I have Ultimate Ears UE-900. I hear ist only with high quality earsphone.
Anyone the same problem?
I had the same issue with various devices such as iPods and various phones using Shure E4C earphones.
The solution or work around was to add some resistance in line after some reading on the head-fi forums a few years ago.
This can be done by getting a 3.5mm to 3.5mm cable and soldering a certain resistor inline (can't remember which),
or an easier cleaner solution, use an inline attenuator/volume control. One comes with the E4Cs so I used this. Turn up the volume on the source/phone/device and use the volume control on the attenuator to adjust to your liking, this should remove or reduce the hissing that is generated whenver the phone/media player's sound system is outputting a signal.
ok guys i got this problem with some headphones :
when i volume up the music to more than 0db using the voodoo audio booster my headphones just like unplug they dont actually unplug but its the same effect, the music stops and turns on again in 1-2 sec with like -30db. I got this problem with the SGS 2 headphones plugged into my SGS 1.
Did you set some sort of volume limit in the voodoo control app?
First wow dude 0 dB is loud. I have only even approached -10 dB using it as line-out, up near -20 dB on headphones is ear-splitting.
Second the -30 dB is the jack plug-in safety option. You can turn it off in the voodoo control app but it is activating because the headphones are being 'unplugged', which is the real problem.
ok so first my limit is +5db , and i know its loud i had never listened that loud to my last headphones ( the original SGS ones) and i dont know but i think the problem is not that much in the hardware but in the software. When i even get close to 0db the sound gets real crappy, and when i connect it to the laptop and turn them really loud the sound is perfect so the headphones dont have like a limit or something because i have several audio boosts on my laptop too. What i am trying to say that the problem is not in the headphones, and when i try get my music on the phone to more than -5db it sounds like -15db or something like that any ideas ? i think i have 3 options
1) problem in the phone
2) problem in the headphones
3) problem with the voodoo app
ohh and the other day i used these HTC headphones they had a button on the mic and when i listened to the music the sound was crappy and they were unplugging when i got my music to 0db but when i press and hold the button the quality was perfect and they were not unplugging. So again anyone any ideas
This isn't a bug, more of a ICS/JB feature that is somewhat annoying.
I have sensitive ears, so whenever I listen to music on my phone, I keep the volume at one unit above muted. If that sounds confusing, think of it as muting the phone, then pressing the volume up button exactly once.
I noticed that at this setting, the volume is considerably louder than in CM7 at the same setting. I understand many people actually appreciate this, but in my case, it's loud enough that I end up having difficulty hearing external noises, i.e. someone calling my name from across the room, or the doorbell ringing.
Is there any sort of app or setting that I could use to fine-tune the volume even more? I would like something that is analogous to the in-line headphone volume control I use on my PC. On my PC, I use the Windows settings to put the volume at 20%, then I use the rotary slider on my headphone wire to fine-tune, adjusting up or down depending on whether I'm on skype, playing a game, watching a movie, etc, without changing the Windows volume from 20%. If there's some way to do this on Android, that'd be great.
You ought to be able to do that, using DSP manager or a media player with an equalizer, such as PowerAmp.
...
Yeah dsp manager is your best option. Easy to use as well

Forgot to check back on this thread. Thanks guys, DSP Manager's equalizer worked.
When my phone is connected via Bluetooth to my car's hands-free kit, some audio could do with being made a little louder.
For example the navigation prompts from Google Maps are plenty loud enough, but some audio-book MP3s played via MD Player and phone call audio could do with being a bit louder.
I have the volume on the Note 8 and the hands-free kit on maximum.
Is there a way I can apply an audio boost when connected to that particular Bluetooth device (or have it controlled via Tasker)?
There seem to be lots of audio boost/control apps in the Playstore, but many seem to allow control of volume for a device without the ability to boost the volume above "normal".
I tried "Precise Volume (+EQ/Booster)", but the boost function didn't seem to make any difference.
If it makes any difference, I'm using Android Auto when connected to the car.
Bump - Anyone?
the only app in the play store that I have found that actually boosts the volume on this phone without being rooted is one called "volume Booster Goodev"
be careful, though, as it can really crank the volume up..
Thanks for that .... had been looking for a volume boost on the headphone out without rooting and this seems to do the job perfectly.
I recently got this smartphone, and one of the very first things that I noticed is that volume thru headphones is very low, this affects the 3.5mm jack, USB-C audio and even bluetooth. It is in fact much lower than on the previous Redmi 9 which I compared with.
Doing some measurements (by playing a tone and measuring with a multimeter) I found that if I plug a male to male 3.5mm jack to the headphone, it will play audio thru, however none of the settings for headphone will be enabled (meaning that the phone doesn't think that I'm using headphones) if I then connect headphones using an adapter it will play at full volume no problem.
The 3.5mm2 jack puts out 0.8Vrms when there is no headphone, and 0.25 Vrms when it detects headphones. (way too low for many headphones).
This means that the phone has a feature that lowers its max volume by 10 dB when using headphones, that is why it also affects bluetooth audio.
For those that want to test it, if you plug a 3.5mm2 extension cord to the headphone jack, and then you plug headphones you will find out that the max volume is much much louder.
Hopefully there is a way that I can remove that feature all together.
I already tried changing the region, disable absolute volume, etc. None of that worked.
Follow up:
I found that what causes the problem is the equalizer effect that Xiaomi added to the phone.
Every time that the smartphone detects headphones it enables the equalizer, the equalizer has a range of +10dB and -10dB.
They implemented the EQ in such terrible way that +10 dB is actually -10 dBFS and -10 dB is -20 dBFS.
So if I increase the volume at say 100 Hz, it is now able to output 0.8 Vrms at 100 Hz. However if I increase the volume in all bands the EQ does nothing and it stays at -10 dBFS. meaning the issue is still present.
There is no option to disable the EQ, it is just flat by default but they didn't add an option to turn it off.
Edit: I tried disabling com.miui.audioeffect thru ADB and while it was disabled, the volume is still low.
No idea if there is another APK that I could try.
