HDA hardware incorrectly identified

This entry is messed up...

iec958:CARD=Q9000,DEV=0
   QuickCam Pro 9000, USB Audio
   IEC958 (S/PDIF) Digital Audio Output

The 16K, 1 channel that pulse is picking up is the mic from my USB
camera. The description appears to be wrong but the sound is coming
out the S/PDIF correctly.

iec958 should be on CARD=Intel, not CARD=Q9000.

Intel = HDA hardware
Q9000 = Quick Cam Pro with just a mic.

So how do I debug this?

Previous comment is incorrect, I was booted on 8.04. But pulse is still getting it wrong.

I was booted on 8.04 when I ran that command. It is correct on 9.04. But pulse is still getting it wrong.
This is on 9.04.

I believe I've found a fix for this. This is broken in pulse 9.14 used in 9.04 beta

In module_hal_detect.c...

    device = libhal_device_get_property_int(u->context, udi, "alsa.device", &error);
    if (dbus_error_is_set(&error) || (device != 0)) {
        goto fail;

The check for (device != 0) should not be there. My device is device #1.

Lennart does not like this fix. He has fixed it differently in current pulseaudio git.

Err, was it committed in the past five minutes? I certainly don't see it
in git HEAD. The fix I pulled is c3b0d841d19898cd268a65173b6c0ca5f88a64c7.

I just managed to get pulse git head building. He has taken a completely different approach to fixing this. The code was already in git.

If you start the pavucontrol app there is a new tab for Configuration. Under that tab you can choose from a drop down...

analog in + sdif out
stereo out
...

This is a way better solution it reads the valid configs out of the HDA hardware and then lets you choose.

Any hope of getting a more recent pulse in? Not being able to easily get S/PDIF working with pulse on Ubuntu has been bugging me for three years.

We're way past FeatureFreeze. I wish I could just ask for 0.9.15 to replace the existing 0.9.14, but our release managers may have a cakefest. In any event, Luke (themuso) does package 0.9.15 in his PPA.

That patch above is in the category of it makes my system work but it breaks other systems. So he has everyone turned off.

This bug was fixed in the package pulseaudio - 1:0.9.14-0ubuntu17

  [ Daniel T Chen ]

    - 0048_fix_stuck_prebuf.patch (LP: #355825)

  [ Luke Yelavich ]
  * debian/control: Drop recommends from the pulseaudio-module-x11 package. if
    they were dropped previously, they were re-added somehow, so lets get rid
    of them once and for all.
