Opti 931: Med931 ver.2.0

Opti 931: Med931 ver.2.0

[hugo.ferreira]

Hi,

I’ve been having a hell of a time trying to make the ALSA drivers for an ISAPnP Opti 931 based card to work. My sound card is a Med931 (Color Expert) ver.2.0. I have been looking around for more information and have the following questions:
 
 1.	I am using kernel 2.4.8 (from Mandrake 8.1). In the ftp sight I came across kernel patches. My question is do I have to apply these patches? BTW, I only found patches for 2.4.7 and 2.4.9. Does this mean 2.4.8 is not supported/tested or its ok.
 
 2.	I also found in the patches section a patch for the Opti 931 chip. It was submitted on the 2002-05-07 by Michael Corlett and assigned Jaroslav Kysela. Its status is still open. Does this mean it still has not been applied to cvs or is not included in rc2 of ver. 0.9.0? A simpleton’s question: how is the “status” classified? 
 
 On a more general note, could someone out there that has the Opti 931 working give me a hand on this? Specifically I would like to know if the driver’s pnp detection was on or if the isapnp tools where used. Please note that I have successfully bused the OSS drivers and am using the same settings with the ALSA drivers to no avail.
 
 TIA,
 Hugo Ferreira.

no, as long as you compile alsa-driver externally from alsa-driver
package, you don't have to apply a patch to the kernel.

the patch was already in cvs.  but i'm not sure whether it was already
fixed on rc2.  please try the cvs version.
you'll need to update alsa-lib, too, if you use the cvs drivers.

i could help for general fixes but such a hardware specific problem is
difficult to handle without the card in hands...

perhaps Massimo, the original author of opti9x drivers, can help
better.  (now cc'ed, too)

you don't need to use isapnptool, because ALSA/kernel do have internal 
isapnp support

now I'm going to test the patch committed to CVS (on all opti9xx chips), 
and I'll let you know as soon as possible.

I downloaded the cvs version and attempted the “cvscompile” in the
driver, libs, tools and utils. Unfortunately I could not compile the 
lib because of an error. Seems to be occurring in the control/ 
control_shm.c file. I have attached the output for you to see.

I am sorry I took so long to answer but my disk was full and I had
to move some stuff around to be able to compile ok.

I would like to confirm the following though:
1. All I need to do is a “cvscompile”, the modules will be 
automatically installed (no need to depmod –a for example?).
2. I need not remove the rc2 compilation output (no “make clean” 
necessary?)

TIA,
Hugo Ferreira.

hmm, not found.  did you forget to attach it actually?

anyway, to track down the bug, we need the precise information about
your environment - which distribution, glibc, and kernel version,
etc.

perhaps that was the reason -- disk full.

no.  cvscompile does only compile.
after that, you need to install the drivers by running "make install"
as root.

no.  the very latest makefile on alsa-driver will remove all old
modules before installation.


ciao,

Takashi

I'm using the following commands to compile and install the USB MIDI
driver:

~/alsa-driver/usb# make snd-usb-midi.o
~/alsa-driver/usb# cp snd-usb-midi.o /lib/modules/2.4.18/kernel/sound/usb/

(modify file/directory names appropriately)

This only works if the package already had been installed, and if the
changes only affect one module, but this seems to be just what you want
to do.
