Hi all,

I'm very to happy to report a major milestone in the 1.0 testing: I've
been able to bring up LiveSupport Studio and play output on two sound
cards simultaneously!

As it turns out, my problem was that I was using a USB sound card that
didn't work. Just out of curiousity, I tried a different USB sound card (a
Sound Blaster Extigy USB), and got system sound out of it.

Using cat /proc/asound/cards, I was able to see that the system correctly
detected and identified the sound cards I have installed. In my case it
looks like:

root@chachi:/home/douglas # cat /proc/asound/cards
0 [Extigy ]: USB-Audio - Sound Blaster Extigy
Creative Technology Ltd. Sound Blaster Extigy at
usb-0000:00:1d.1-1.2, full speed
1 [I82801CAICH3 ]: ICH - Intel 82801CA-ICH3
Intel 82801CA-ICH3 with YMF753 at 0x1c00, irq 9
2 [Modem ]: ICH-MODEM - Intel 82801CA-ICH3 Modem
Intel 82801CA-ICH3 Modem at 0x2400, irq 9

The number at the beginning of each card tells you the /dev/dsp value you
have to use in the LiveSupport Studio config file, which is located in
/opt/livesupport/etc/gLiveSupport.xml. I changed the following lines to
read:













Once I changed those lines, I was able to play properly, with the output
of Live Mode going to my default sound card, the Extigy USB, and the
output of the cue going to my notebook's onboard Yamaha AC-XG, which the
system identifies as ICH - Intel 82801.

For me, the debate over whether to use ALSA or OSS is completely beside
the point, as I'm using ALSA's OSS emulation.

I still don't know why ALSA-style "plughw:0,0" and "plughw:1,0" don't work
(main output is coming out choppy when I specify "plughw:0,0", and cue
output doesn't work at all). I'll be curious to find out what others have
come up with.

Hi all,



I'm very to happy to report a major milestone in the 1.0 testing: I've been able to bring up LiveSupport Studio and play output on two sound cards simultaneously!



As it turns out, my problem was that I was using a USB sound card that didn't work. Just out of curiousity, I tried a different USB sound card (a Sound Blaster Extigy USB), and got system sound out of it.
