Description Valerio Vanni 2023-11-27 19:26:57 UTC
System is a Debian 11 amd64, kernel 5.10.201, DVB-T board is an Hauppage WinTV-quad.

If a DVB-T streaming is being played (i.e. I'm watching TV channels in Kaffeine) and I suspend to ram with /usr/sbin/pm-suspend, when system resumes DVB play is unable to continue.
Closing and reopening kaffeine doesn't help.

The only thing I can do, then, is:
-close kaffeine
-rmmod cx23885
-modprobe cx23885

I attach a boot dmesg, a suspend / resume without DVB play, and another with DVB play active.
