Hi,
I have a system with multiple monitors and would like to send notification sounds to the monitor on which corresponding window is visible.
For a workstation and a tiny computer things look different:
- workstation (Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz):
00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06) 00:03.0 Audio device [0403]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller [8086:0c0c] (rev 06) 00:1b.0 Audio device [0403]: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller [8086:8c20] (rev 04)
Here alsa show me two cards:
- HDA Intel PCH (Realtek ALC671)
- HDA Intel HDMI (Intel Generic)
**** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDA Intel HDMI], device 3: Generic Digital [Generic Digital] Subdevices: 1/1 Subdevice #0: subdevice #0
Is a proper kernel config (CONFIG_SND_HDA_CODEC_HDMI) enabled?
It was missing and adding it helps a lot. Would there be a way to auto-select it when corresponding DRM driver is selected?
Kind of select SND_HDA_CODEC_HDMI if SND_HDA or at least mention it in description, maybe as conditional comment is done for HDA codecs.
The device name looks strange as if it's not properly bound with the HDMI codec driver.
With SND_HDA_CODEC_HDMI enabled I get better results on the tiny computer (not checked on workstation yet):

Shown by aplay -L as: ... hdmi:CARD=PCH,DEV=0 HDA Intel PCH, HDMI 0 HDMI Audio Output hdmi:CARD=PCH,DEV=1 HDA Intel PCH, HDMI 1 HDMI Audio Output hdmi:CARD=PCH,DEV=2 HDA Intel PCH, HDMI 2 HDMI Audio Output hdmi:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 3 HDMI Audio Output hdmi:CARD=PCH,DEV=4 HDA Intel PCH, HDMI 4 HDMI Audio Output
Alsamixer shows me 5 S/PDIFs (S/PDIF, S/PDIF 1, ..., S/PDIF 4) which is not that helpful. Why don't alsamixer and aplay -L at least use the same naming scheme? If the naming there would match output naming as show by xrandr (or /sys/class/drm/... it would be even better!
xrandr: HDMI-1 disconnected (normal left inverted right x axis y axis) DP-1 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 1439mm x 809mm HDMI-2 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) HDMI-3 connected 3840x2160+3840+0 (normal left inverted right x axis y axis) 1872mm x 1053mm DP-3 disconnected (normal left inverted right x axis y axis)

Testing each output with aplay I could determine that hw:0,7 (currently) matches DP-1 (as reported by xrandr) and hw:0,8 matches HDMI-3 (as reported by xrandr).
Though while testing often the first sound played never reaches the monitor's speakers, only a second run shortly after the first reaches speakers. (played sound is rather short: aplay -D hw:0,7 /usr/share/sounds/purple/receive.wav same with slightly longer login.wav)
