We should test Jaroslav's duplicate-wakeups fix first.
I'll devote some cycles to the latter bug report this coming week.

The jack-in-main bug report has been filed (#510481); Luke and I have
both worked on and reviewed it, so now it's awaiting approval from
Martin.
Xine and PulseAudio at least will gain this backend immediately for testing.

There are reports that the symptom can't be reproduced with a new
user. I've never been able to reproduce it with a fresh user; YMMV.

Should we be considering a timidity->fluidsynth migration, then?

I don't know if an extra button in the GUI will do much; there are
certainly UI arguments either way. Perhaps we should ask the Ubuntu
Desktop team to evaluate reenabling the non-pulse mixer perspective in
a separate binary package for 10.04.

The HDA ones are fairly straightforward; the AC'97 ones are a bear.
But yes, I patch them [the former ones] as they're reported.

Actually needs some alsa-lib love; I've added this to the top of my
queue this week.

We need to be clear that the alsa-source binary package (used with
module-assistant) generated by alsa-driver has non-Free drivers
stripped:
* Removed because of DFSG violations:
- alsa-kernel/pci/cs46xx/cs46xx_image.h
- alsa-kernel/pci/cs46xx/imgs
- alsa-kernel/pci/korg1212/korg1212-firmware.h
- alsa-kernel/pci/maestro3.c
- alsa-kernel/pci/ymfpci/ymfpci_image.h

I think the ubuntu-audio-dev team may be more appropriate, as it's a
more focused group of individuals.
Best,
