A couple of hardware problems

A couple of hardware problems

[Steve Harris]

The first one is not a problem with alsa, but I haven't been able to find
any mention of it online, so I wonrdered if anyone has any insight into it.

I have a motherboard with a via82xx chipset [KT333] on it, the bios will
only alow me to select "auto" or "disabled" for the sound device, and
neither seems to make the device appear to lspci, Is it possible that the
motherboard is disabling it becasue it's detected my other soundcards?

The other I dont know about: I bought an ESS Solo1 based card (Terratec
128i PCI) to use the MIDI port, but it doesn't appear to work for MIDI
input. I've been messing with it for a couple of days and I'm ready to
give up and swap it for an old ens1371 based card. If anyone has anything
I should try before swtiching it please say.

My alsa-driver version is "based on the experimental CVS version of alsa,
the source was downloaded on 20021216.102029", as supplied by CCRMA.

yes, usually "auto" means to activate the chip on mobo only when no
other soundcards exist.

the last time i tried, i also couldn't get the midi-in working, and
forgot this issue for a while.  i just took a look at the code again. 
could you test the attached patch?  it's to the latest cvs but likely
applicable to your version, too.

Thanks. I wonder why the mobo is not giveing me the "enabled" option it
mentions in the docs. Oh well.

OK, I'l try to apply it this evening. I could sort of get some input (the
Rx bytes number in /proc/asound/card0/midi0 went up) when I opened the
lowlevel device for writing with dd and sent midi in, it didn't seem to be
going up reliably though.

I managed to aaply the patch, but it caused a kernel panic. I'm going to
have to install a card I know works 'cos I'm against a bit of a deadline,
but I can post you the card if you dont have access to one.
