 |
|
OK, I'm in just a little over my head, so if anyone could help me out, that'd be great.
I have a "Creative Sound Blaster Live! Value" card and I'd like to have it work with ALSA and without OSS. As I understand it, I should have ALSA emulate OSS for programs not yet using ALSA. (This is where I'm in over my head.)
Thusly, I compiled my 2.6.7 kernel as follows:
| Code: | <M> Advanced Linux Sound Architecture
<M> Sequencer support
< > Sequencer dummy client
<M> OSS Mixer API
<M> OSS PCM (digital audio) API
[*] OSS Sequencer API |
I have my USE flags to include alsa and to exclude oss.
Then, from the ALSA Guide, I emerged alsa-utils and didn't emerge alsa-oss.
Since I compiled my own kernel, I checked my devfs.conf, made sure alsa loaded at boot, started it up right now, and went to unmute the volume... huh, there's an error:
| Code: | root:/$ amixer
amixer: Mixer attach default error: No such device |
So I do as much checking as I know how:
| Code: | root:/$ lsmod

I can't seem to get the card recognised, though the modules seem loaded. Why is that? |

andrewski,
It looks like the snd_emu10k1 module isn't loaded but all the ALSA OSS emulation modules are.
That is, your apps can talk to the OSS emulation layer but the emulation layer can't talk to the hardware because the ALSA module for the hardware is missing.
Its under
Sound
Advanced Linux Sound Architecture
Oops (edit)
PCI devices
and choose EMU10K1 (SB Live! & Audigy, E-mu APS) if you forgot to configure it.
Maybe your ALSA config file is not right, because it should be loaded from there.

Nope, that wasn't compiled in my kernel... oh man... 
(I had been looking for Creative.)
Now everything's working fine! |
