Bug#867548: Available for Additional Testing

[Bryan Cebuliak]

Since update  from  Buster to  Bullseye on  hard  disc  and  on  live  USB
  boot  when  using Built-in Audio Digital Stereo(HDMI 2) on  playback for
Youtube  and  other   video streams I  have   noticed variable skipping of
audio and  video ,  audio  out of   sync, video racing   at   fast  forward
pace.  This    does  not   happen    when   playback  is  on Built-in
Audio Analog Stereo.  However  I   would  like  audio  to  come  through
the  HDMI  device [TV].  Using  the  left over old  Debian 10 kernel on
the   Bullseye   system still  shows   same   problem.  Ubuntu 20.04  on
the   same   system has  no  issues.  What  is  the  regression  from
Debian 10  to   11?  I note  the  configuration Analogue  Stereo Duplex
is   unavailable in  the  Bullseye  version  but  available  and  selected
in Buster. Changing  to  and  from  this  in Buster causes no problems  in
playback
Your  bleeding user
