Greetings:
I'm preparing a final draft of an article re: ALSA and I started
wondering about whatever happened to modules.conf. In my old RH9 (2.4
kernel) I was able to freely manipulate the ALSA modules (designate for
loading, reorder, set alias, etc) via /etc/modules.conf. Things have
changed a lot in 2.6.x, and /etc/modules.conf is apparently not to be
edited in Ye Olden Way. Is there a similar single file in the 2.6 file
system ? If so, where is it ? On my Debian Etch system I have this file :
/etc/modprobe.d/sound
It looks like the file to change a la the old-time modules.conf, but my
entries have no effect. Is there another file located elsewhere that I
should be editing ? Here's my /etc/modprobe.d/sound :
alias snd-card-0 snd-ice1712
options snd-ice1712 index=0
alias snd-card-1 snd-emu10k1
options snd-emu10k1 index=1
alias snd-card-2 snd-virmidi
options snd-virmidi index=2
Also, what's the status of a user-friendly ALSA control and operations
panel that might address such matters as ordering multiple soundcards,
write/edit .asoundrc, start/stop ALSA services, etc. ? Is the ALSA
development group pursuing anything like that ?

Hi Dave,
On my Gentoo systems (and I think many other distros) it's now
modprobe.conf but it's not generally edited directly. On my systems
there are subdirectories with numerous files, such as
/etc/modules.d/alsa, where you make the entries for the specific type
of modules you are interested in. Under Gentoo you then run a program
(on Gentoo it's modules-update IIRC) which collects all these files
together into /etc/modprobe.conf and at the same time does some
checking to ensure things are somewhat correct.
HTH,
Mark

Mark is right, you must edit /etc/modutils/alsa (make sure you don't
have backup files from your editor such as alsa~ lying around,
everything in that dir is used...). Then run update-modules to transport
the changes into modules.conf.
Also: /etc/modprobe.d/sound should be a copy of (or symlink to)
/etc/modutils/alsa(-base). This makes the correct information show up in
/sys/module/snd_usb_audio/parameters/*. I found this important if you
want to control the order of your usb devices.

Hi Dave. On FC1 using the 2.4 kernel the file was /etc/modudes.conf, and if
for example you have a usb midi keyboard, you have to create an alias for
snd-usb-audio, and create 2 options lines, so as to load the sound card
first, and snd-usb-audio second. This is due to the USB starting early in the
boot process, and Alsa wrongly seeing the usb midi keyboard using
snd-usb-audio as a soundcard, and loading it as card 0 if you don't set the
options.
FC2 and later using the 2.6 kernel use /etc/modprobe.conf, and for FC2 the as
above applies regarding setting options lines if you are using a usb midi
keyboard.
FC3, 4, and 5 have fixed the problem regarding the usb midi keyboard, when I
booted these post install the sound card worked, and the usb midi keyboard
was also ok. I'm in FC2 at the moment, but I'm pretty sure that snd-usb-audio
doesn't even show up in /etc/modprobe.conf, just the sound card (Ihave only
the 1).
In Debian Sarge, and Etch, I've always added snd-usb-audio, and the 2 options
lines to /etc/modutils/sound , which updates, (and I think I've got the
filename right) /etc/modprobe.conf, which specifically tells you not to make
changes in it, as anything in /etc/modutils will
overwrite /etc/modprobe.conf. I've also seen folks saying to
use /etc/modprobe.d/sound, which obviously works. Perhaps it doesn't matter,
and you can use either method.
Sorry I can't help with the other ???'s, but the multipurpose Alsa control
panel sounds a nice idea.
Nigel.
Also, what's the status of a user-friendly ALSA control and operations
panel that might address such matters as ordering multiple soundcards,
write/edit .asoundrc, start/stop ALSA services, etc. ? Is the ALSA

Hi Dave. Apologies. I missed the point you made about your additions
to /etc/modprobe.d/sound NOT working.
Secondly. I've booted up Etch to check the files, and can confirm that in my
case, with one sound card, and the usb midi keyboard, it looks like this
in /etc/modutils/sound.
alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
alias snd-card-1 snd-usb-audio
options snd-usb-audio index=1
Then running update-modules, updates the file /etc/modules.conf (sorry I had
the filename wrong before. It is not /etc/modprobe.conf).

AFAICT, every distro does this differenly.

No one is working on anything like this.
You can set the default soundcard with gnome-sound-properties - it
creates an .asoundrc that sets the default device.
There should really be no need to reorder sound cards as they can be
addressed by name. It's best to fix the apps that are hardcoded to talk
to the first device.
I'm not sure what you mean by "stop/start ALSA services". ALSA does not
run any daemons and config file changes take place immediately.
Users should really not need to modify .asoundrc. If the default does
not DTRT it's a bug. What use cases do you have in mind?

/etc/modprobe.d/sound
is correct.
