Salve, quando collego la tv con hdmi funziona solo l'uscita video. Con alsamixer e pavucontrol non ho risolto, non viene proprio rilevato l'audio hdmi. In questo momento uso Ubuntu 20.1 ma lo stesso problema era presente anche in 20.04 Grazie

No :( Avevo già visto questa discussione, a me l'uscita hdmi non compare per nulla su pavucontrol

potrebbe essere un problema derivato dai driver grafici?

proviamo a impostare i parametri nel file(se non c'e' crealo):

/etc/modprobe.d/i915.conf

inserendo: options i915 enable_fbc=1 enable_guc=3

e riprovare

Ancora come prima :( Non so se c'è uno specifico modo con cui scrivere quello che mi hai suggerito di inserire

per vedere se ha preso i parametri riesegui:

sudo systool -m i915 -av

e controlla se:

enable_fbc=1

enable_guc=3

sudo update-grub

  • riavviare e rieseguire: sudo dmesg | grep -iE "huc|guc|dmc"
