Title:
[SOLVED] No HDMI sound on ATI HD6450A, ALSA card is recognized
Status in “alsa-driver” package in Ubuntu:
Fix Released
Bug description:
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 Radeon HD 6450A HDMI device (open-sourse
"radeon" driver is used, video through HDMI output is fine) - this
HDMI sound does not work. Now I need to use HDMI sound output. Ubuntu
13.04 x64 kernel 3.8.0.21 generic.
HDMI sound card #2 appears in alsamixer, but with 1 controller called
"S/PDIF" (not muted) - which is strange. There is not HDMI/DP or other
controllers for this card.
PulseAudio (System settings - Sound settings) does not show the HDMI
card/sink in the list, although it shows some "S/PDIF" sink, which
does not related to HDMI.
aplay -l DOES show this HDMI card - see below. It shows card #2:
Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
"aplay -Dplughw:0,0 ~/test.wav" - plays perfectly through analog ALC622 card.
"aplay -Dplughw:2,3 ~/test.wav", "aplay -Dhdmi:2,0 ~/test.wav" - gets an
error "Error opening device - no such device".
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.
Also attached alsa-info.sh ans aplya -L outputs.
