Title:
[SRU] Increase recording quality
Status in HWE Next:
Fix Released
Status in alsa-utils package in Ubuntu:
Fix Released
Status in alsa-utils source package in Focal:
Fix Released
Bug description:
[Impact]
Audio gets recorded by "arecord" has really bad sound quality when the volume
is low.
[Fix]
https://github.com/alsa-project/alsa-utils/pull/69
Switch the default audio format from 8 bits to 16 bits if hardware supports
it.
[Test]
1. Plug a microphone.
2. Run `arecord | aplay` and say something to the microphone.
3. Only noise can be heard.
With the fix applied, the recording is clear.
[Where problems could occur]
If there's any hardware falsely advertised to support 16 bits, this change
will break them.
However, this is effectively using `arecord -f cd` or `arecord -f cdr`, so
that's not likely.
