Frank,
I don't think you need to send the file. So far this is sort of what I'm
doing by hand, but it isn't working. I can stop audio apps, then stop Alsa,
remove everything from memory (I think), and then restart Alsa. Alsa starts
up cleanly with no error messages, but sound does not return.
As I said earlier, I think there *may* be two other things going on here:
1) The sound card hardware is a strange state after the driver does bad
things to it.
2) alsasound start does not apparently reset the hardware completely.
I can understand #2 conceptually since the reboot sets up PCI addressing
and does other things to the card. If the driver was to mangle the PCI
address of the card (I'm not suggesting it does, but just for instance) then
I suppose the driver could not and should not try to fix that. My problem
right now is I cannot see what's getting messed up, so I do not know how to
reset it.
Luckily it's a pretty fast machine and a reboot is only about 45 seconds,
but it's frustrating to have to shut down email and other things to do it.
Thanks much,
Mark
