Title:
UA-101 - UA-101,
Thank you for reporting this bug to Ubuntu.
Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.
See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases
We appreciate that this bug may be old and you might not be interested
in discussing it any more.
There was a bug with multichannel duplex where the number of output and
input channels are different, which should be fixed by:
http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/src/modules/alsa?id=02dc6d84edde7af86e155b224b6aa98080ef2979
That fix has not been released into Ubuntu yet,
Thanks for the log. Looking at the log, PulseAudio seems to do the right
thing. It first tests input:multichannel, which succeeds, then
output:multichannel, which also succeeds, but when then trying full
duplex, we get an error back from the kernel:
I: [lt-pulseaudio] (alsa-lib)pcm_hw.c:

Hi David, Raymond, thanks for your follow up. Here is more pertinent
information:
Changing from Multichannel output to Multichannel input on the
Output tab in gnome sound settings makes the UA-101 output device
disappear completely and permenantly and it does not appear in the Input
tab. The only

* Synchronizing the playback rate to the capture rate is done by using

* Submitting a playback URB therefore requires both a ready URB and

capture at same tone

Hi Joe and thanks for testing,
However, the git binary doesn't detect my motherboard's onboard HDA
Intel PCH sound card (like the default pulseaudio in ubuntu does)
This could be because we have removed extra-hdmi.conf. There might still
be a udev rule referencing extra-hdmi.conf as this is
Thanks David,
The symlink you mentioned fixed the detection of my onboard sound card
and with pulseaudio-git it shows SPDIF and Headphones outputs and a
Microphone input and they both work as expected. The installed ubuntu
pulseaudio also has an Analogue audio output that isn't shown in the
gnome

I've done a quick compile and test of the pulseaudio git head code on Ubuntu
14.04 and it does indeed now autodetect and automatically sets up the
multichannel audio outputs - running the compiled pulseaudio git binary detects
the UA-101 and sets it up as a 7.1 multichannel audio output device
Upgrading to Ubuntu 14.04 fixed the issue for outgoing sound only.
Inputs (Microphone, etc.) are still not available, but I didn't have
time yet to test if there is a workaround how to get it working.

Upgrading to Ubuntu 14.04 fixed the issue for me. :-)
Sound is available, without the need to manually apply the workaround or
changing configurations, etc.
So you should consider upgrading to Ubuntu 14.04.
But now I am still fighting with the proprietary NVIDIA graphics card
driver in 14.04

I'm seeing the same problem with my UA-1000 (which uses the UA-101
driver). I think the OP has covered all the bases, but I'm pasting the
lsusb - for this device since it is a different model number. Let me
know if you want any other info.
