Public bug reported:
There are 2 integrated soundcards presents in Lenovo Q180 PC - one based
on analog ALC662 chip and works fine (sound works), another card (#2) is
a part of ATI Redeon HDMI driver (open-sourse radeon driver is used,
video HDMI output is fine) - this HDMI sound does not work. Now I need
to use HDMI sound output. Ubuntu x64 kernel 3.8.0.21 generic (latest in
mainstream repos).
HDMI sound cards appears in alsamixer, but with 1 controller called
"S/PDIF" - which is strange. Not muted.
aplay -l DOES show this HDMI card - see below. It shows card #2: Generic
[HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
aplay -Dhw:2,3 test.wav gets an error - Cannot open file or device.
PulseAudio does not show the card/sink in the list, although it shows
some "S/PDIF" - most probably related to ALC662 card.
pacmd list-cards DOES NOT list any HD-Generic or ATI cards. Only the
ALC662 analog one. pacmd list-sinks DOES NOT show any HDMI-related sink.
Aslo attached alsa-info.sh output.
