Bug Description

Binary package hint: gnome-media

I have two soundcards, one AC'97 and one ESI Juli@. When I boot up Karmic AMD64 Beta, Live-CD, and start gnome-volume-control, on the hardware tab both cards are correctly listed as "Analog stereo duplex". However, on the Input tab, only the AC'97 (listed as "Internal Audio") appears (expected both soundcards).

Workaround: If I then go to the hardware tab, and switch profile for ESI Juli@ first to "Analog stereo output" and then back to "Analog stereo duplex", then switch to the input tab, both soundcards are listed as devices.

So, as you can see pulseaudio loads the sink only after having changed back to "Analog stereo duplex".

As a side note, recording works fine with programs such as QARecord (with alsa device=plughw:CARD=Juli) both before and after the profile change.

Could this be two bugs in one? One is in pulseaudio - not loading the source for Juli@, but then, shouldn't gnome-volume-control detect that, and set the profile to "Analog stereo output" instead of "Analog stereo duplex" then...?

For what it's worth, perhaps a pulseaudio -vvvv could help analyze what is going wrong.

Some more research: The error messages I see in my pulseaudio.log are very close to what I see in this bug:
And, both of us have ICE1724 sound cards.

This patch to the linux kernel fixes the underlying issue for me.

Can confirm the exact symptoms of the original problem, including the workaround.
Can also confirm that applying the patch to the ice1724 driver solves the problem.
