I have a small Pico ITX motherboard with an Nvidia ION2 chipset with both HDMI
audio out (TV) and Stereo/Composite Audio out (Stereo.) You can run it with
Composite Audio output, or HDMI audio output, but not both simultaneously, an
not without heavy reconfiguration. The sound card is an Nvidia Chipset.
While I can independently get the HDMI audio output working individually, or
get the Front speaker Jacks working, I can't get both of them working at once
without locking up some older 32 bit programs.
Here is the output of aplay -L
null

here is the output of aplay -l

Now as I said, I can get either the Composite playback working by having no
asound.conf setup, or, an asound.conf setup like this:
pcm.dmixer {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0660
slave {
pcm "hw:0,3"
rate 48000
channels 2
period_time 0
period_size 1024
buffer_time 0
buffer_size 4096
}
}
This will make just HDMI work.
I tried using dmix to make it output both as a joined socket, but the result
was SDL lockups. Here is the configuration I used
pcm.2asone_NVSB_dmix {
type dmix
ipc_key 170300
# "hw:0,0" is Card 0 Device 0 - ALC1200 Analog
# Change this line bellow to accord you Analog Device
slave.pcm "hw:0,0"
}
pcm.2asone_NVHDMI_dmix {
type dmix
ipc_key 170310
# "hw:0,3 is Card 1 Device 3 - ATI HDMI
# Change this line bellowto accord you HDMI Device
slave.pcm "hw:0,3"
}
pcm.mic_dsnoop {
type dsnoop
ipc_key 15645
slave {
# "hw:0,0" is Card 0 Device 0 - ALC1200 Analog
# I use the mic plugged in the Analog Card
# Change this line bellow to accord you Mic Device
pcm "hw:0,0"
}
}
