   In the first case, the music plays, and in the second, it doesn't.

   $ aplay -l / $ pasuspender -- aplay -l

   In dmesg, I did not find anything interesting, except for this. Should
   there be front headphone and speakers or just front headphone?

   Hi, Pavel,
   Â
   Standard advice is to try aplay ALSA command while suspending
   PulseAudio/PipeWire.
   Â
   Also please check your dmesg log for anything strange.
   Â
   Thank you,
   Geraldo Nascimento
