Hi there,
since i updated to kernel 5.5 i have no sound over hdmi anymore (GeForce
RTX 2070).
With the previous kernel 5.4.14 everything is fine.
Although i got sound with speaker-test -D hdmi:CARD=NVidia,DEV=2 -c 2 -r
44100, pavucontrol shows all hdmi sound devices as unplugged.
I bisected it down to this commit
(5398e94fb753d022301825ebfa5f7cf8a660d8eb) and changed the line
HDA_CODEC_ENTRY(0x10de0093, "GPU 93 HDMI/DP", patch_nvhdmi)
to
HDA_CODEC_ENTRY(0x10de0093, "GPU 93 HDMI/DP", patch_nvhdmi_legacy)
Now it's working again. I'm not sure if this is a problem with
pulseaudio or if the RTX 2070 does not support the mentioned codec.
Thanks in advance
Martin
