 Posted: Tue Aug 28, 2012 11:42 pm Post subject: ALSA w/ USB and multiple sources? |
 |
|
I have a Sound Blaster X-Fi Go! Pro USB sound card (primarily because my onboard sound won't work with OSX) that I'm having trouble with on Gentoo. My onboard sound is disabled, but my NVidia GTS450 has an HD audio device that can't be disabled and it keeps taking the default slot with ALSA. Alsamixer sees both devices and I can switch back and forth, but I just can't get any sound out of my USB device.
Asus Sabertooth X58
Gentoo AMD64 stable (w/ GCC 4.6.3)
Gnome 2.32
USE="alsa gnome etc"
NVidia GTS 450
Alsamixer shows the following at F6:
- (default)
0 HDA NVidia
1 USB Device 0x46d:0x8b2
2 Sound Blaster X-FI Go! Pro
enter device name
/etc/modprobe.d/alsa.conf below:
| Code: | # Alsa kernel modules' configuration file.
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
## OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##
# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
## OSS/Free portion - card #2
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
# Set this to the correct number of cards.
options snd cards_limit=1 |

There's a few different ways. Personally, I favour using ~/.asoundrc, because there's plenty of other customizations to put there also - see my sig for an example.

You've just mentioned having 2 or 3 audio cards, so set that to 3.

My modprobe.d file looks like this, you probably just want to put usb-audio before hda-intel:
| Code: | options snd cards_limit=8
alias snd-card-0 snd-au8830
alias snd-card-1 snd-hda-intel
alias snd-card-2 snd-hda-intel
alias snd-card-3 snd-usb-audio
alias snd-card-4 snd-aloop
alias snd-card-5 snd-aloop
options snd-au8830 index=0
options snd-hda-intel index=1,2
options snd-usb-audio index=3 id=Headset
options snd-aloop index=4,5 enable=Y,Y |

Do you have the snd_usb_audio module loaded? |
I don't know if it was loaded, but I loaded it with modprobe and restarted /etc/init.d/alsasound. That would do it, right? No joy.

Sorry, yes, I had it set to 3 at one point but completely hosed the file and started over. I forgot to change it back to 3 before I posted, but it was correct at one point in my fiddling.
Will try all of the above suggestions and report back. |

Ok, thanks for all the replies. After a couple of days of playing around with asound.conf I finally got it working.
However, this REALLY should not be this much trouble. I've been playing around with Linux, OS/2, and other alternative OSes as a hobby since 1994 just because I like a challenge and I like to break things, but this really is too much. You would think with all the advances in usability the OSS community has made in the last several years it wouldn't take a small feat of engineering to select a sound device. Somebody really needs to work on this.
Again, thanks for the help. |
