Hi!
I am the guy with the alsa problem you remember me ? Well, I recompiled alsa, this time without any unresolved symbols... . Don't work right, but I installed a second card from which I know that it worked well, but this card cannot output something ( the hardware-outport is broken [ ooups ] )... .
This is my modules.conf:
alias char-major-116 snd
alias snd-card-0 snd-ens1371
alias snd-card-1 snd-es1938
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
# Es1371
#alias sound-service-0-0 snd-mixer-oss
#alias sound-service-0-1 snd-seq-oss
#alias sound-service-0-3 snd-pcm-oss
#alias sound-service-0-8 snd-seq-oss
#alias sound-service-0-12 snd-pcm-oss
# ESS-Solo1
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-8 snd-seq-oss
alias sound-service-1-12 snd-pcm-oss
#
options snd major=116 cards_limit=2
options snd-ens1371 index=0
options snd-es1938 index=1
----
Everything seems to work fine, except that alsa uses my broken card, the ES1371 for audio output.
If I set jack to Playback via the card with index 1 , so my ESS-Solo1 (snd-es1938):
# jackd -d alsa -d hw:0 -P hw:1
Jack just prints out the helpscreen, and if you have a look by yourself:
...
-P,--playback [name] playback output and optionally set the playback device (default: duplex)
...
[name] can be "optionally set (to) the playback device", in my case hw:1, so my second card with card index 1, see modules.conf. Why this jack-error ? And any idea why sound-output is not piped by alsa generally ??
Thx for attention
Sascha Retzki
