Split Sound

Greetings to all,

Not too long ago, I use to be able to specify my line in port to be used as a second output port with alsamixer, and use it independanty from my laptop (built-in) speakers. An update seems to have 'fixed' this functionality, and I was wondering how to get it back...

Any help?

Thanks

Re: Split Sound

Oh, also my sound card:

     Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)

aplay -l also says:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

[Edit] been looking further into this, head -n 1 /proc/asound/card0/codec* says:

Codec: SigmaTel STAC9205

however I cant find its entry in /usr/src/linux-2.6.29-ARCH/sound/drivers/Kconfig

Re: Split Sound

Sure has been a while for this thread. I have used Oss since for most of my needs, but I have went back to ALSA now, because I need to have one program be able to use both line out, and headphone/speakers independantly (mixxx), which oss does not allow.

anyway, here's the content of my modprobe.conf:

#
# /etc/modprobe.d/modprobe.conf (for v2.6 kernels)
#

options i915        modeset=1
options usbcore        autosuspend=1

alias net-pf-10 off

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-hda-intel

# module options should go here
options    snd-hda-intel    model=laptop    enable=1    index=0

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
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

based on Arch's ALSA setup wiki.
