I got this phone to replace my previous phone mainly because of the Bluetooth audio. I use it in my car a lot. Now I'm using the nexus and I have to say the quality is worse than anything. If it's plugged in with aux, it's fine. But Bluetooth audio is completely crap. Do you guys know if this can be a software fix?
Bluetooth audio quality

IMHO bluetooth is designed for convenience not quality. I use BT for car all the time but my speakers are even crappier so no difference. If you care go for wires. I saw the review on gsmarena for the audio of N4 quite positive.

Bluetooth sounds fine on mine. Can you be a little more forthcoming about what you're hearing (other than "crap").
Speakers cracking. I thought it was my speakers but then I plugged in the aux and it was perfect. I used gnex, 2 phones ago for audio streaming music and it was fine. But this is just crazy terrible. Night and day. The crackling is extremely noticeable
If you have sizzling in your bluetooth audio I would look to ground loop issues. Perhaps an audio transformer between the bt audio out and your stereo.

Bluetooth audio sounds better than my Gnex did. Using AOKP 12/05 build. I do wish there was AVRCP 1.3 support, but that seems to be missing from 4.2 roms so that's not so much a device specific issue.
A2DP is a ****ty spec from a quality standpoint. It uses lossy encoding and was designed to have low overhead while sounding acceptable. It's not going to be stellar on any device.

Donavo, there is a known issue with Bluetooth on Android 4.2.
Actually three issues that people are having. First are connection issues, second is audio drops and the third is the audio quality {the crackling that you are hearing).
The issue apparently is caused by a rewrite of the Bluetooth stack by Google for v4.2.
Both my Galaxy Nexus and Nexus 7 have the cracking issues after upgrading to 4.2. It's less noticeable on low quality source material like podcasts but very noticeable on high quality material.
No connection, drop issues with the GNex but I have drop issues on the N7.
You'll have to use the headphone jack until a fix is released. If there's a custom rom that's not using the new Bluetooth stack then that would fix the issue as well.
Here's the bug report if you want to track it.

EDIT: It may not have been a rewrite but they may be using a new stack from Broadcom.

I have the bluetooth audio quality problem too. Just got a Nexus 4, upgrading from a Hercules (Tmo SG2). On the previous phone, sound quality was excellent and you would never know audio was streaming from the phone. With the Nexus 4, the sound is harsh and distorts on the high frequencies, resulting in a static sound on things like cymbals and such. Also, the phone audio streaming over bluetooth is harsh. It's almost as if the person on the end was talking through a megaphone.
I did notice that while in a phone call, the volume was much louder to my receiver than my previous phone. Perhaps the problem is that the bluetooth audio's volume is being sent too high?
I hope Google fixes this soon, along with the broken AVRCP profile (I no longer get song meta data streaming to the receiver).

It's not broken, it just hasn't been implemented. I believe stock Android just has AVRCP 1.0 which is control only. I think you need v1.3 to get titles to show. I don't believe any of the Nexus phones have AVRCP v1.3 which is a shame. Until Google puts it in I think you need to go with a custom rom to get AVRCP v1.3. Maybe do a quick search to see which do. I'm using stock so I don't know which ones support it.
Wow, I didn't know this. Being stuck at 1.0 is ridiculous. Maybe (hopefully) with the Bluetooth framework change they'll finally get around to adding 1.3 (or hell maybe 1.4!) support.
I'm using a crappy, $13 dealextreme bluetooth receiver (SKU: 120198). The audio quality is obviously not as good as with the aux input, but I think it's rather good. I can say for sure that it sounds considerably better than my GNex did on the same receiver. It does occasionally have connection problems, though I'm not sure if that's a problem with the phone or a side-effect of buying a $12 receiver, lol.
just posted a similar question in the evo 3d forums, part still waiting for my N4, but my evo sound quality over bluetooth is poor too, and I can hear the compression! its worse on high quality music like flac files. I think it is a general limitation of bluetooth audio streaming

Yeah this sux bad....i noticed the audio quality instantly after syncing my Nexus 4 to my car. I was as if you took a 320kbps MP3 and compressed it to 64kbps. I flashed back to stock in hopes of fixing it but no dice. I cant wait for a Fix
This is the only thing that makes me miss my Galaxy Nexus (4.1.2)

Sent from my Nexus 7 using xda premium2There are some sound mods in the development section, is there anyone which will improve the bluetooth streaming quality? It's really annoying that my 2.5 year old desire sounds much better than my brand new n4
I talk to the developer for 1 of those mods and he tried to push the 4.1 Bluetooth stack over but it's not compatible with 4.2. So he said there's nothing he can do

Smile now cuz this fix actually works. I was having the same issue and none of the other fixes worked. I did the manual install and dont forget to set permissions.
