ALSA - pnp OS bios option

[Nick Warne <nick@linicks.net>]

Hi all,

On New Years eve my CPU (Athlon 1200 ams3b) died.  I managed to get a 
replacement off e-bay.  During my diagnosis of what happened, I reset BIOS, 
so obviously when I got the replacement I had to set it all up again.


Info: 2.6.15, on base Slack 10 (updated a lot from source).

If I turn OFF PNP OS, when I boot, 'alsactl restore' (run from rc.local) 
squinnies:

Set_Control:894 Name mismatch ... Control #47
896: Index mismatch (0/0) for Control #47
1008: Bad control.47.value

Then I messed with alsamixer/aslactl store~restore etc. and all appeared OK in 
console - but sound is all messed as if no restore was done.  And I get the 
same error on boot again.

Turn ON PNP OS in BIOS, and all works again, alsactl restore works fine.

Now, after the issue I had with my CPU dying, I hate keep rebooting to test 
this, but the tests I done appear as above.

So, is this something else?  Or do I need to set PNP OS in BIOS for ALSA?
