I'm setting up a new PC and hope to use the Planet CCRMA packages for some simple home recording projects. The PC has a 64-bit processor, so I've installed the x86_64 version of Fedora 10. I've done the basic steps of adding the Planet CCRMA repositories and installed their real time kernel, so I'm think I'm ready to try and get started.
First, I need to get my sound cards set up right. I have an M-Audio Delta 1010LT card, which I'd like to use for working with music and the Intel HDA card built in to the motherboard, which I'd be happy to use for things like system notifications and other incidental sounds. Here is what the system tells me about the cards:
# cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf9200000 irq 22
1 [M1010LT ]: ICE1712 - M Audio Delta 1010LT
M Audio Delta 1010LT at 0xb000, irq 20
Here is my modprobe.conf:
# cat /etc/modprobe.conf
alias snd-card-0 snd_hda_intel
options snd-card-0 index=0
options snd_hda_intel index=0
alias snd-card-1 snd_ice1712
options snd-card-1 index=1
options snd_ice1712 index=1
I listed the Intel card first, since the CCRMA installation instructions say that the first one is "usually the default device used by all programs", and I figured that if some application decides to make an unexpected noise, then I don't want it going through my music system; in other words, I'd like to choose what I send through the Delta 1010 card. Does that make sense?
Here's what is happening so far: I get no sounds out of my speakers except when I go to the KDE System Settings|Multimedia and test some of the output devices. The list of devices, which I can order differently for Notifications, Music, Video, etc, shows these:
- HDA Intel (ALC883 Analog)
- M Audio Delta 1010LT (ICE1712 multi)
- HDA Intel (ALC883 Digital)
- PulseAudio Sound Server
The only ones that produce any sounds when I test them are the HDA Analog device and the Delta 1010 device, but the weird thing is that output seems to be coming out of the built-in output jack (on the motherboard) in either case. Does the OS route output from the Delta 1010 through the built-in card to its output jack? Also, I've connected only the first two RCA analog outputs from the Delta 1010 to my desktop speaker system - should I use a different pair of outputs for testing?
Playing a CD directly from the CD drive works, but playing music files from Amarok does not.
I'll leave it at that for now. I posted the information above to the Planet CCRMA mailing list threee days ago, but I haven't gotten any responses. Does anyone here have any suggestions for what I should do next?
