A bug was filed to bugzilla.kernel.org for a quirk of some models which
ALSA BeBoB driver supports.
Bug 199365 - repeating bus resets on Firewire bus with Focusrite Saffaire 26/io
https://bugzilla.kernel.org/show_bug.cgi?id=199365
Some models (two models as long as I know) have a quirk to disappear from
IEEE 1394 bus at disconnections of packet streaming. Corresponding
character devices are removed according to 'remove' callbacks of relevant
drivers from Linux dd core. Then the models re-appear on the bus by
generating bus resets and corresponding character devices are added
according to 'probe' callbacks from Linux dd core.
In a view of ALSA applications, this looks that plug-out/plug-in occur in
a sequential order for the models when they stop playback/capture substream.
For most applications, this doesn't cause large issue. However, this quirk
is not good for combination of below modules in PulseAudio. PulseAudio
enters endless loop to detect the models and start/stop PCM substream.
- module-udev-detect
- module-alsa-card
- module-suspend-on-idle
In detail, please read my comment no.6:
https://bugzilla.kernel.org/show_bug.cgi?id=199365#c6
This commit suppressed udev detection of sound card for the issued models.
For the models, 'PULSE_IGNORE' flag is added to udev rules, then
module-udev-detect don't handle the models and PulseAudio never uses the
models automatically. In a scenario for users to load
module-alsa-card/module-alsa-sink/module-alsa-source by hand, although
these modules can still stop PCM substreams with module-suspend-on-idle,
PulseAudio never enters the endless loop because udev detection doesn't
work for the models. In this case, as long as special files for ALSA
character devices for these models are the same, corresponding sinks and
sources are available even if the voluntary plug-out/plug-in occur.

The iec958 output uses device 2 and the iec958 input uses device 0. The
USB configuration in alsa doesn't set up the device numbers correctly,
which is why we need custom configuration in PulseAudio. Ideally this
would be fixed in alsa, but trying to get help for that wasn't
successful.
This is based on a patch by Rolo <rolo@wildfish.com> that replaced the
old ID with the new one. I deemed it better to leave the old ID in use
(I can't verify if the old ID was correct or not).
The original commit message:
Every time I reinstall or update Ubuntu I have to make this change
to get it to recognise my Native Instruments Traktor Audio 6
external soundcard.
Each time I remember the change by hunting down this forum post in
German,
https://forum.ubuntuusers.de/topic/traktor-audio-6-erkannt-aber-nicht-anwaehlbar/3/#post-8759808
(I don't speak German).
I'm not sure if the ID is just incorrect or if perhaps the hardware
identifies itself differently on slightly different models, so
perhaps we need to duplicate the line - I'm well outside of my
comfort zone here and I know barely anything about how hardware
works on Linux but figured if it helps me it would help others so I
should put it forward.
Thanks!
This reverts commit ca63fbc1d8.
I applied the patch too hastily. force-speaker.conf is supposed to be
used only when the alsa mixer doesn't contain any elements that would
indicate the existence of a speaker port, but the reverted patch is a
workaround for a different problem. On the two affected EeePC machines
the Headphone element needs to be unmuted when using speakers. The
analog-output-speaker-always path happens to do that, but that's
unintentional. analog-output-speaker was changed[1] to mute the
headphone output when using the speaker port, and
analog-output-speaker-always should have been changed too, but that was
forgotten.
The kernel driver is buggy if it has a Headphone mixer element that
mutes both headphones and speakers, so this should be fixed in alsa. If
we end up having a workaround in PulseAudio for the broken driver, it
should be implemented with a new profile set and path configuration
files.

There are one headset jack on the front panel of TB16, through this
jack, we have one stereo headphone output (hw:%f,0,0) and one mono
headset-mic input (hw:%f,0,0); and there is one speaker output jack
(hw:%f,1,0) on the rear panel of TB16.

Added Dell Inspiron 3420, 3520 and Vostro 2420, 2520.
Note that this is only necessary for kernels 3.3 to 3.5, as 3.6
has phantom jack support.

Several laptops have speaker ports, and/or internal mic ports, but we have
no way of detecting that. So we make the port(s) always show up for these
devices.

For Nvidia and Intel, support probing of up to four HDMI devices.
Also add port information to all HDMI profiles.

The thinkpad ACPI driver sometimes creates a virtual sound card,
which at best exposes a volume control. Save some startup time, and
unnecessary error messages in the log, by ignoring it.

The Kinect shows up as a UAC device after the firmware has been loaded,
but in order to be detected by pulseaudio a 4-channels input only
mapping is needed. Provide a new profile for that and set it with a udev
rule.

Now that subset mixer paths are removed, this workaround is no longer needed.
This effectively reverts 1c38b5d478 but due
to me forgetting to add files and adding a couple extra workarounds after,
it's easier to just do this manually rather than run git-revert.
This is a workaround - these usb headsets have one output volume
control only, labeled "Speaker". This causes the default profile
set to not control the volume at all, which is a bug. Workaround
that by creating a separate profile set.
