I haven't the slightest clue what you're asking. I'm using PulseAudio
as it comes with Ubuntu, configured for my number of speakers using the
GNOME Volume control panel.

I have had to clear my log files 3 times now in the past day because my root filesystem was full, which started breaking various things (like my postfix installation which gets my mail delivered directly to me).

There may be more in the log files than I have seen, simply because of the amount of stuff there. For anyone who requests the files, I'll email them: note that the log files are to 4 MB. However, they will expand to somewhere around 9 GB; compression on my system (4x 2.2 GHz 64-bit cores) took 300 minutes each, compressing with pbzip2. If you have a multiple-core system, decompression will go a lot more quickly if you use pbzip2 instead of bzip2 (and note also that compression took about 5 hours, I'd expect decompression to be similar). I will attached trimmed-down versions of these files as well, shortly after uploading the full log files.
