Hi all.
I'm a bit stumped in my efforts to get ALSA sound working...
and I've been unable to find much in the way of docs for ALSA
(No "man alsa", /usr/doc/alsa* adds up to a couple examples, several
copies of the changelog, and some copyright info... and alsa-project.org
seems to have little or nothing beyond the "sound-card matrix"). Any
help and/or pointers to (helpful) docs would be greatly appreciated...
So here's the problem:
--The short version--
I've installed alsa v 0.9 to drive my Creative Labs SBLive! 5.1,
and it seems to think it's working:
miguel# /etc/init.d/alsa start
Starting ALSA sound driver (version 0.9.0beta10): emu10k1.
Restoring ALSA mixer settings...done.
miguel#
But I have no sound. When I run alsaconf it exits with an error saying:
amixer: Mixer attach default error: No such file or directory
Could not initialize the mixer, the card was probably
not detected correctly.
miguel#
--The long version--
Please forgive me if I include irrelevant stuff or leave out key info...
I'm still rather a newbie. So here's everthing that I thought might be
relevant...
I installed alsa-base 0.9+0beta12, alsa-modules 0.9+0beta10, and
alsa-utils 0.5.10-1... This required me to upgrade to kernel 2.4.16-686.
Done (and verified with uname that that is the currently booted kernel).
I established that my card (SBLive! 5.1) is called emu10k1, and
told ALSA to use that module...
lsmod has this to say:
snd-card-emu10k1 1952 0 (unused)
snd-emu10k1 47200 0 [snd-card-emu10k1]
snd-pcm 46176 0 [snd-emu10k1]
snd-timer 9056 0 [snd-pcm]
snd-rawmidi 11456 0 [snd-emu10k1]
snd-hwdep 3456 0 [snd-emu10k1]
snd-util-mem 1184 0 [snd-emu10k1]
snd-ac97-codec 22848 0 [snd-emu10k1]
snd-seq-device 3744 0 [snd-card-emu10k1 snd-rawmidi]
snd 23336 0 [snd-card-emu10k1 snd-emu10k1 snd-pcm
snd-timer snd-rawmidi snd-hwdep snd-util-mem snd-ac97-codec
snd-seq-device]
soundcore 3556 2 [snd]
(Including only the results that look (to my untrained eye) relevant.)
lspci says this:
00:12.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07)
00:12.1 Input device controller: Creative Labs SB Live! (rev 07)
(again showing only the obviously relevant entries)
Now when I run alsaconf, it doesn't detect my card; so I choose SB Live
off the list, hit okay, hit enter a few times to accept the identifier
CARD_0, the max. dac 128, max. adc 64... Then it says:
OK, 1 card(s) configured.
will prepare the card for playing now.
Now I'll run '/etc/init.d/alsa start', then I'll use 'amixer'...
Then we get this response:
Loading driver:
Starting ALSA sound driver (version 0.9.0beta10): emu10k1.
Restoring ALSA mixer settings...done.
Setting the PCM volume to 100% and the Master output volume to 50%
amixer: Mixer attach default error: No such file or directory
Could not initialize the mixer, the card was probably
not detected correctly.
And every time I log in to Gnome, or launch Gnome's mixer applet, I get
a popup error saying "couldn't open mixer device /dev/mixer". When I
try amixer as root or regular user, I get more of "Mixer attach default
error: No such file or directory".
Now, I *know* the card is good because it works (beautifully) under
WinXP (Dual-boot machine... I haven't made a clean break so far)...
So... please somebody give me a nudge in the right direction.
Many thanks,
Chris
