Hi Robert,

Good questions on the sound configs. We'll have to make this more=20
user-friendly in a future version, but for the meantime, here's a couple=20
of tips.

First, to find out which cards are assigned to which positions, open a=20
terminal and type:

cat /proc/asound/cards

and you will get an output that looks like this:

root@chachi:/home/douglas # cat /proc/asound/cards
0 [Extigy ]: USB-Audio - Sound Blaster Extigy
Creative Technology Ltd. Sound Blaster Extigy at=20
usb-0000:00:1d.1-2.2, full spe
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

where 0 corresponds to /dev/dsp, 1 corresponds to /dev/dsp1 and so on.

There are two places where LiveSupport sound card configuration is kept.=20
The scheduler soundcard info is in the XML config file is in:

/opt/livesupport/etc/scheduler.xml

Look for the following lines:





The LiveSupport Studio config info is in:

/opt/livesupport/etc/gLiveSupport.xml

Look for the following lines:













You can then change these files to set which sound card is going to be=20
used for which function. It's probably a good idea to make a backup of=20
these files before making any changes.


Hope this helps,

doug

Hi Doug and developers!=20

At last, I have refreshed version of LS project. The problem I had before, =

considering=A0 duration of complete cvs updating and it's compiling, is now=
=20
solved in much better and more practical way (thanx to my new radio pirat=20
colleague Sebastian)!=20

But now I have new confusion:=20
I have 3 audio cards that have been easilly recognized by our=20
debian-package Knoppix LS, and arranged by it's importance:=20
0 - SoundBlaster Live=20
1 - Realtek AC97=20
2 - Mackie XD-2 Spike professional card on USB=20

It's now hapenning that LS program take one configuration of audio cards,=20
like:=20
0-is master (on air) and 1-is slave (cue). Ok it works, but if I start=A0=20
shedule mode it inverts their positions and importance,
and it plays things that are for Cue on On-air card and stuff like that.=20
How can I set this definitely in our system - which sound card is where=20
and on what way can I set my studio ?=20
Can we have some tool in LS like "preferences" tab for sound card - so=20
that it can prevent=A0 different functions of LS=A0 to change configuration=
s=20
of sound cards?=20

I'm still not sure if this is a bug, because my colleague and I have=20
thoroughly examinated drivers in order to make Mackie Spike card work in=20
0-position, as a professional On-air. So maybe on this way=A0 we have=20
damaged its permanent configuration or something like that.=20
