'[OT]: Linux Sound Problems'
2002\08\15@154234 by Dipperstein, Michael

face picon face
I have a Linux soundcard question, and after getting nowhere with the
Linux-Sound list, I figured the likelihood of getting worse results from the
PICList would be pretty slim.  I apologize in advance for the length of the
post.

I have NEC Ready 9732 which I running RedHat Linux version 7.1.  From time
to time I make attempts to get the sound card work, but the only time sound
has come out was when I tried several successive drivers using "sndconfig
--noprobe".

However after sndconfig exits, I'm back to no sound.  I've tried following
the manual steps in the sound-how-to, but I need to supply many driver
options which aren't clearly explained anywhere.

When sndconfig runs, it tries to load the ad1848 drivers, but has errors
while running modprobe, then I get stuck and have to kill sndconfig to get
out of it (somebody, maybe me, needs to make an exit option).

My computer dual boots, so I was able to get this information form windows
control panel.

Here's where my attempt at getting my sound card to function now stands:

1) No luck with sndconfig (see above).

2) Installed isapnptools

3) Used pnpdump -c to create a /etc/isapnp.conf

4) Edited /etc/isapnp.conf so that the following lines are uncommented:
(CONFIGURE AZT3011/-1 (LD 1
(IO 0 (SIZE 16) (BASE 0x0220) (CHECK))
(IO 1 (SIZE 8) (BASE 0x0388) (CHECK))
(IO 2 (SIZE 4) (BASE 0x0534) (CHECK))
(INT 0 (IRQ 5 (MODE +E)))
(DMA 0 (CHANNEL 1))
(DMA 1 (CHANNEL 0))
(NAME "AZT3011/-1[1]{AUDIO               }")
(ACT Y)
))


(CONFIGURE AZT3011/-1 (LD 2
(IO 0 (SIZE 2) (BASE 0x0330) (CHECK))
(INT 0 (IRQ 9 (MODE +E)))
(NAME "AZT3011/-1[2]{MPU401 MIDI         }")
(ACT Y)
))

5) Added the following lines to /etc/modules.conf
alias sound ad1848 irq=5, io=534, dma0=1, dma1=0
alias sound-slot-0 ad1848
alias midi opl3 irq=9 io=330

6) Rebooted, making sure isapnp ran.

Still no go.

Here are some hints that I hope will help somebody point me in the right
direction:

modprobe -v sound and modprobe -v sound-slot-0 provides no information.

modprobe -v midi results in:

/sbin/insmod /lib/modules/2.4.9-34/kernel/drivers/sound/opl3.o
Using /lib/modules/2.4.9-34/kernel/drivers/sound/opl3.o
Symbol version prefix ''

The first time, nothing on successive tries.  Is the midi not being installed
properly?

/proc/isapnp shows both audio and midi to be active.

When I halt the system, I get this message:
Saving mixer settings modprobe: modprobe cannot locate module
sound-service-0-0 aumux: error opening mixer.

Is there are sound-service-0-0, I should also include in my module.conf?
What does it do?

I would be grateful for any tips or pointers.  Even an RTFM followed
with a link to TFM.

-Mike

Hello Michael,

Did you try getting the latest alsa-project files and make sound work
with those ?

Dincer,

I've looked at the alsa-project, but my Sound4 (Aztech) card was not listed as
either supported or not supported, so I passed.

I'll read the howtos and give it a try this weekend.

Thanks,
-Mike
