Comment 36 for bug 986817

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 audio mixer settings when using pulseaudio-git, though I'm guessing this is either an alias for the onboard Intel 5.1 or perhaps pulseaudio-git has jack insert/removal detection... anyway the sound works through headphones and mic as expected.

I've attached the output of pulseaudio-git when run with -vvvv.

To provide a clean log I first removed ~/.pulse, ~/.pulse-cookie and ~/.config/pulse, then did the following to ensure pulseaudio doesn't autospawn:

mkdir ~/.pulse
echo "autospawn=no" >> ~/.pulse/client.conf
pulseaudio -k
./src/pulseaudio -vvvv --log-target=newfile:pulseaudio.log

Steps taken after running pulseaudio-git are as follows:

1. Wait for pulseaudio to settle then turn on UA-101 with manual switch on the device
2. Wait for pulseaudio to settle then open gnome audio settings
3. Highlight UA-101 in gnome audio settings to make it the default output ("Play sound through")
4. There is a button on the gnome audio settings window that allows me to change from "Multichannel output" to "Multichannel input" - I change this and the UA-101 device disappears from the overview and seemingly with no way to get it back except for deleting anything pulseaudio related from my home directory and restarting pulseaudio.
5. Close gnome audio settings and turn off the UA-101 before killing pulseaudio.

The UA-101 doesn't have any alsa controls at all - nothing is picked up in alsamixer. In Windows, the 10 input and output channels are controlled by a software mixer. I'm wondering if this is why the inputs are not detected by pulseaudio?
