I have it working and the audio is just fine.  For a long time my audio
was terrible, sounded like an MP3 file at very low compression rates.
On the front end, Utilities/Setup - Setup - TV Settings -
Recording Profiles - Software Encoder (v4l based):

in the Live TV setting, last page, make sure it's not set to MP3 for the
codec. Change to Uncompressed 48000.
