hi,

i need snd-usb-audio install cause i'm using an uc-33e:
http://www.qbik.ch/usb/devices/showdev.php?id=2428

i have build my kernel without alsa and oss, because i've installed alsa-driver, alsa-tools, alsa-utils, alsa-header with emerge. here's my lsmod:

usb_midi 22500 -
snd_seq_midi 6400 -
snd_pcm_oss 48352 -
snd_mixer_oss 17248 -
snd_seq_oss 34336 -
snd_seq_midi_event 5984 -
snd_seq 51760 -
snd_ice1712 60036 -
snd_ice17xx_ak4xxx 3008 -
snd_ak4xxx_adda 5376 -
snd_cs8427 8448 -
snd_ac97_codec 73344 -
snd_pcm 81476 -
snd_timer 21156 -
snd_page_alloc 7492 -
snd_i2c 4768 -
snd_mpu401_uart 6496 -
snd_rawmidi 19936 -
snd_seq_device 7020 -
snd 44068 -
ohci_hcd 16424 -

where can i find the module snd-usb-audio?
i tried modprobe snd-usb-audio, nope...

From the 2.6.10 kernel:

Code: Select all

#
# USB devices
#
# CONFIG_SND_USB_AUDIO is not set
# CONFIG_SND_USB_USX2Y is not set

Compile it as module (or whatever would work best for you).

Code: Select all

less /usr/src/linux/.config | grep CONFIG_SND_USB_AUDIO

now i understand a bit more. i didn't compile ALSA in kernel, not even as module, because i wasn't able to install "emerge alsa-driver" (conflict with kernel)... so i didn't turn on ALSA on in the kernel, but i did an emerge alsa-driver, tools, utils and all the stuff. but it seems that emerge alsa-xxx didn't install snd-usb-audio! what should i do. right now, i'm trying to build only ALSA (M) and SND_USB_AUDIO (M) nothing else in alsa (cause i should have it from the emerge alsa).

what is the best way to deal with this?

Dunno... I use OSS.

well i found something, if you want snd-usb-audio module, you have to add this to your make.conf:
ALSA_CARDS="usb-audio"

and then emerge alsa-driver again.

the problem, is the documentation say:

If you use a 2.6 kernel, you may use the drivers provided in the kernel, but we still recommend that you use media-sound/alsa-driver as they are more up to date than what is provided in the kernel tree.

so, if you want to use emerge alsa-driver you have to disable ALSA in the kernel. and then compile alsa-driver with emerge. no luck, my UC-33e it still not working. it's an usb midi device (no audio). plug and play normally. more later.

I got a similar setup working right now. I have both an Audigy2 ZS for normal sound and a Yamaha UX16 USB Midi interface. I have managed to get them both working, using the kernel modules method and also using the alsa-driver method.

In my make.conf, I have both of my cards listed:

Code: Select all

ALSA_CARDS="emu10k1 usb-audio"

I have them in this order because emu10k1 is my primary card used for pcm. (I don't know if this actually makes any difference)

I managed to get it sortof working with the alsasound script but it was buggy so I dumped the script and loaded snd-emu10k1 (audigy driver), snd-usb-audio (UX16) and snd-pcm-oss (for oss compatibility) in /etc/modules.autoload.d/kernel-2.6. Then I run "alsactl restore" in /etc/conf.d/local.start and "alsactl store" in /etc/conf.d/local.stop.

That worked until I updated to kernel 2.6.11 then the modules wouldnt load. To fix this, I just built the appropriate modules directly into the kernel. I then removed my entries from /etc/modules.autoload.d/kernel-2.6.

I hope this helps somehow

it helps a lot my friend! thank you very much, adding usb-audio in make.conf compiled the module snd-audio-usb! also, i've put virmidi in make.conf so i can load snd-virmidi.

thank you very much, now i have the perfect box for doing audio.
