i915, HDMI/DP audio with multiple monitors

[Bruno Prémont]

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
 card 1: PCH [HDA Intel PCH], device 0: ALC671 Analog [ALC671 Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0


- tiny computer (Intel(R) Core(TM) i5-6500T CPU @ 2.50GHz):
 00:02.0 VGA compatible controller [0300]: Intel Corporation HD Graphics 530 [8086:1912] (rev 06)
 00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-H HD Audio [8086:a170] (rev 31)

 Here alsa shows a single card:
 - HDA Intel PCH (Realtek ALC671)

 **** List of PLAYBACK Hardware Devices ****
 card 0: PCH [HDA Intel PCH], device 0: ALC671 Analog [ALC671 Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
 card 0: PCH [HDA Intel PCH], device 3: Generic Digital [Generic Digital]
   Subdevices: 1/1
   Subdevice #0: subdevice #0


How can I determine/set to which monitor the sound should go, and preferably send
different sounds to both monitors at same time?


Cheers,
Bruno

There should normally be multiple HDMI devices (one for each HDMI/DP
connector more or less). Eg. my hsw shows:

card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Looking at the hda_codec.c we see:
 static int audio_idx[HDA_PCM_NTYPES][5] = {
...
        [HDA_PCM_TYPE_HDMI]  = { 3, 7, 8, 9, -1 },

So you always get those device numbers, but I don't see an immediate
relationship between those and the pin numbers (which do have some
kind of relationship with the HDMI/DP port). I guess if they always
get registered in order of the pin numbers then those would translate
to 3 == port B, 7 == port C, etc. And after that the problem is figuring
out which port is related to which connector, for which we have nothing
at the moment.

I suppose the ideal solution might be to have a sysfs symlink (or
something) to connect the two together.

But then there's MST where I think the pcm device correlates with the
crtc rather than the connector. Maybe. I can't remember anymore, and
I'm not sure it even works (I've recently heard people saying it
doesn't).

Is a proper kernel config (CONFIG_SND_HDA_CODEC_HDMI) enabled?
The device name looks strange as if it's not properly bound with the
HDMI codec driver.

On AMD systems, there are vendor verbs to do the channel mappings for
various configs.

Intel may have something similar.

This requirement is reasonable :)

Ville is right. For NON-MST (PCM static assignment), the PCM & PORT 
mapping is simple and static.

For DP-MST (PCM dynamic assignment), it is a little complicated. In HDMI
audio driver, the per_pin saves all the information. 
1. PORT info: per_pin->pin_nid is related to the PORT information. 
The mapping information is showed in hdmi audio driver function 
intel_pin_eld_notify(). 
2. PCM info: we can get the PCM with per_pin->pcm_idx.

With these information, we can tell which PCM is mapped to which PORT.

The audio driver can export such information to user space (No sure 
if such information is already exported.). And user space, such as 
pulseaudio and so on, can use such information automatically choose 
which PCM to playback corresponding to the monitor 
which active window is in.

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.

With SND_HDA_CODEC_HDMI enabled I get better results on the tiny
computer (not checked on workstation yet):

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)

 card0-HDMI-A-3 -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-3


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)

Bruno
