 Posted: Thu Aug 19, 2004 11:29 pm Post subject: Booting different sounddevices in a particular order! |
 |
|
Hello I have a SB Live and a Bt878 Tv-Tuner that also has a
soundcard in it. If I enable this sound as Modules in my kernel this soundcard will bott first and most programs wont be working with sound anymore. This is because Alsa loads my SB LIVE as the SECOND card. I dont want this. I want SB LIVE to be my First! soundcard that is loaded. How do I get Alsa to load my sb live as the first card ?
I have tried this already but no luck.
options snd_emu10k1 index=0
options snd_bt87x index=1
alias sound-slot-0 snd-emu10k1
alias sound-slot-1 snd-bt87x
Thanks for the help.

There is an option, but I don't remember it 
In the meantime you could compile the SB driver into the kernel and load the bt878 as module... |

/etc/init.d/alsasound hope it helps.

just a thought:
maybe it makes a difference if you put this into /etc/modules.conf:
| Code: | alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
|
I know it's part of the OSS/Free portion, but maybe it's still there for a reason.

Your part is interesting but also confusing. I am not sure where excactly to put these lines in the alsasound file. My alsasound file looks a bit different I guess
einfo "Loading drivers ( hacked  "
/sbin/modprobe snd-pcm-oss
/sbin/modprobe snd-mixer-oss
/sbin/modprobe snd_emu10k1
/sbin/modprobe snd_intel8x0
/sbin/modprobe snd-bt87x

i've just removed automatic driver loading and replaced it by this 'hacked' part this way i forced the emu10k1 module to load _before_ intel8x0, so emu10k1 gets /dev/dsp not dsp2. that's all.
just search for the commented part in your alsasound file and replace it as me. it could differ a bit, because i did it some time ago.
good luck

I have
| Code: | ## ALSA portion
alias snd-card-0 snd-ens1371
alias snd-card-1 snd-emu10k1
alias snd-card-2 snd-cmipci
## OSS/Free portion
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
alias sound-slot-2 snd-card-2 |
in my /etc/modules.d/alsa and my ens1371 is always the first!
Do you have tried the snd-card alias thingy?
Otherwise tell the Applications a specific alsa device.
I use mplayer often with 2nd than 1st card:
/opt/mplayer-cvs/bin/mplayer -ao alsa:mmap:device=hw=1
Or when ens1371 is already busy its fed on their second channel:
/opt/mplayer-cvs/bin/mplayer -ao alsa:mmap:device=hw=0.1
Most Programs support specific Device usage...
