Sound card doesn't output to all speakers...

DiZASTiX · 07-23-2004, 12:57 PM

I have 4.1 surround speakers connected to a Sound Baster Live! (emu10k1) and I installed the dirvers sucesfully in Slackware 10 using the alsa config tool, but the only problem is that the sound only comes out of my two front speakrs but not the two rear. (I tested in xmms) I know that all the cables are correct because I get all the speakers working in Windows. Anyway to get this 4.1 to work in linux?

UPDATE:

my driver is in /lib/modules/2.4.26/kernel/drivers/sound/emu10k1/emu10k1.o.gz

I get this when I try insmod emu10k1:

Code:

bash-2.05b# insmod emu10k1.o.gz 
emu10k1.o.gz: unresolved symbol sound_unload_mididev
emu10k1.o.gz: unresolved symbol midi_synth_hw_control

I found this page, and he seems to get both rear and front speakers working but he did the same thing I did, used alsaconf:

any help would be great, thanks!

You may need to look at the mixing in alsamixer. Its possible that some channels are muted. Its also possible that the driver/xmms doesn't know how to upmix stereo sounds into 4.1.

EDIT: do "modprobe snd-emu10k1" instead of "insmod emu10k1"

hey, no result when I try modprobe snd-emu10k1 but this is what I get when I modprobe emu10k1:

Code:

bash-2.05b# modprobe emu10k1
/lib/modules/2.4.26/kernel/drivers/sound/emu10k1/emu10k1.o.gz: init_module: No such device
/lib/modules/2.4.26/kernel/drivers/sound/emu10k1/emu10k1.o.gz: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.26/kernel/drivers/sound/emu10k1/emu10k1.o.gz: insmod /lib/modules/2.4.26/kernel/drivers/sound/emu10k1/emu10k1.o.gz failed
/lib/modules/2.4.26/kernel/drivers/sound/emu10k1/emu10k1.o.gz: insmod emu10k1 failed

I will look into the alsamixer that you are talking about and see if anything is wrong for now...

thats good. No output means the module has been insertted correctly. I am recommending snd-emu10k1 over emu10k1 because emu10k1 is the old OSS driver, while snd-emu10k1 is the newer ALSA driver.

ok great, so how would I go about using this module?

first, make sure it's inserted properly by typing "lsmod". You should see snd_emu10k1 and some other snd_ stuff. Then type "alsamixer" and make sure "master" and "PCM" are unmuted and 100%. Then try playing sounds.

That should get you set up for stereo sound. I don't have 4.1 so I don't know what other levels you have to change. But play around with alsamixer. "surround" should probably do the rear speakers and maybe "master mono" for the subwoofer, but I don't really know.

hey, I did this and I got all the 4 speakers + woofer to work! Thankyou so much for your help.

For anyone else having this problem, they main option I had to play with was "Wave Surround", that got my 2 rear speakers working. All the others I just played with to get better quality.

Again, thanks spuzzzzzzz!

I had it working, I went to Windows and run Creative Scan For Erros and it said I had problems in the Mixer and I said: "fix it" and it got fixed [I had only 2 speakers playing in Windows, I hope now they will be 4].
but now in GNU/Linux I have no sound. I can play with alsamixer but then again Windows will lose 4 speakers.
I really don't care about me and Windows. {I don't use them}. my sister though does
