Public bug reported: [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. ** Affects: alsa-utils (Ubuntu) Importance: Undecided Status: New ** Description changed: [Impact] Audio gets recorded by "arecord" has really bad sound quality when the volume is low.
