Hi, i like very much aosp extended, and other similar roms (for example RR), but i'm a pianist, so i need to record my stuff, and i can't do it with those roms because the sound it's horrible.
The same problem appears when i record whatsapp audio, but if i take a video from the camera app (aosp), the sound it's OK.
What can i do?

Thank you and sorry for my bad english.

Normally it's the video sound that turns out unusable, for recording mostly in crowded places. Can't say anything about simple audio recording.

If you're on Android 6.0.1 like me, you can edit two files:
1. /system/etc/audio_platform_info.xml
...
<acdb_ids>
<device name="SND_DEVICE_OUT_SPEAKER_PROTECTED" acdb_id="136"/>
<device name="SND_DEVICE_OUT_VOICE_SPEAKER_PROTECTED" acdb_id="136"/>
<device name="SND_DEVICE_OUT_SPEAKER_PROTECTED_VBAT" acdb_id="136"/>
<device name="SND_DEVICE_OUT_VOICE_SPEAKER_PROTECTED_VBAT" acdb_id="136"/>
<device name="SND_DEVICE_IN_CAPTURE_VI_FEEDBACK" acdb_id="137"/>
<device name="SND_DEVICE_IN_VOICE_REC_MIC" acdb_id="1"/>
<device name="SND_DEVICE_IN_HANDSET_STEREO_DMIC" acdb_id="1"/>
<device name="SND_DEVICE_IN_HEADSET_MIC" acdb_id="1"/>

</acdb_ids>
...

2. /system/etc/mixer_paths_mtp.xml
...
<path name="audio-record">
<ctl name="DEC1 Volume" value="108" />
<ctl name="DEC2 Volume" value="108" />

<ctl name="MultiMedia1 Mixer TERT_MI2S_TX" value="1" />
</path>
...
<path name="low-latency-record">
<ctl name="DEC1 Volume" value="108" />
<ctl name="DEC2 Volume" value="108" />

<ctl name="MultiMedia5 Mixer TERT_MI2S_TX" value="1" />
</path>
...
note: You can replace 108 with a value that suits you most. The range is 84-120.
