ALSA

[Dave Mielke]

The INSTALL file for the ALSA driver describes a special control file named
"/proc/asound/0/pcmD0o". It says that a line like the following can be written
to this file:

    Playback <app_name> <fragments> <fragment_size> [<options>]

The description of the <app_name> parameter says:

    <app_name> - name of application with (higher priority) or without path

Does anyone know what the phrase "higher priority" here actually means? Also,
what is the syntax for assigning a priority to an application?

Hi people,
	I need your help! I am having a bit of trouble setting up ALSA on
my Dell Optiplex (w/ Redhat 6). I have two cards in the machine; an sb16
built in to the motherboard, and an sb live pci card. Trouble is, I can't
get MIDI working on the sb live. Jazz complains that /dev/sequencer2 and
/dev/music are not configured, and more'ing them just to see what happens
reports the same. I can't even get the sb16 detected (allthough it works
fine with the kernel sound drivers), as isapnp can't find it. I would
really appreciate some help with all this - I've tried just about
everything I can think of. I've included the conf.modules i've been using
and the /proc/modules report.
Thanks v. much,
Ian

PS - everything else on the sb live works ok - its just MIDI that doesn't.

Re: ALSA

[flatmax]

Have you tried the ALSA mail list ?
Although alot of people here use both ALSA and OSS, you might get more
help specifically on ALSA from the alsa mail list or home page :
www.alsa-project.org
OR you could also try the 4front:
www.4front-tech.com

OTHERWISE .... compile your kernel with sound enabled :
1 cd /usr/src/linux
2 make xconfig OR make config
	Build the kernel with sound modules enabled and configured ...
	might require isapnp as well to set up the card at boot.
3 make bzlilo or somehting similar to compile the kernel
4 make modules
5 make modules_install
6 Reboot
7 debug !!!

fuzzies to ya...
