Hauppauge USB-Live2 - Apparent audio regression from linux-media-2012-01-11.tar.bz2 onwards.

Hi,

I have a Hauppauge USB-Live2 ( lsusb -> Bus 001 Device 003: ID
2040:c200 Hauppauge ). Up to and including kernel 3.0.0-16 generic,
video capture does not work with the drivers built into the kernel.
However, since July 2011, when Devin Heitmueller posted this message
http://www.mail-archive.com/linux-media@vger.kernel.org/msg34771.html,
the device has been working fine if the media_build procedure is done
(i.e. git clone git://linuxtv.org/media_build.git; cd media_build;
./build; make install). The problem that I have now is that audio
capture has stopped working if I build and install the current
media_build tree. The output from dmesg looks normal, the ALSA device
Cx231xxAudio [Cx231xx Audio] is present, everything looks in order,
but if I try to use the device I get one loud click then silence.
Building the dated tarballs that I find at
http://linuxtv.org/downloads/drivers/, I find that audio works fine up
to the tarball labelled linux-media-2012-01-08.tar.bz2, but
linux-media-2012-01-11.tar.bz2 seems to introduce the audio problem
which as of last week remained in the latest code. Video capture still
works fine, only audio is affected. It looks like here:
http://git.linuxtv.org/media_tree.git/shortlog is where I should be
able to see logs of what changed between version 2012-01-08 and
2012-01-11, however there appear to be no updates since end of October
2011. Have these logs been moved elsewhere?

Thanks,

Mark

Sorry, seem to have found where the logs have moved to:
http://patchwork.linuxtv.org/project/linux-media/list/

Will try to track down what may have caused the issue.
