Hello.
I've been out of luck trying to work with sound on Linux. My experience
with Audacity, Jack and Ardour haven't been successful at all.
I was trying to create a .asoundrc file as, from what I read, it would
be one of the first necessary steps.
My soundcard is
[cyb_AT_kali cyb]$ cat /proc/asound/cards
0 [Live ]: EMU10K1 - Sound Blaster Live!
Sound Blaster Live! (rev.8) at 0xa800, irq 10
and it's working well and I'm running Mandrake Linux 9.2 with Gnome.
My attempt at editing a .asoundrc file is shown below
pcm.!sb {
type hw
card 0
}
ctl.!sb {
type hw
card 0
}
pcm.jackplug {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}
which I copied and pasted from the Alsa site. Apparently it is working
because when I issued some commands to play a file they worked.
[cyb_AT_kali cyb]$ aplay -d sd docs/voz.wav
Playing WAVE 'docs/voz.wav' : Signed 16 bit Little Endian, Rate 44100
Hz, Stereo[cyb_AT_kali cyb]$ aplay -djackplug docs/voz.wav
Playing WAVE 'docs/voz.wav' : Signed 16 bit Little Endian, Rate 44100
Hz, Stereo
However, Jack is not working properly and when I try to run Ardour all
my running apps are killed and disappear.
Jack shows the following messages:
JACK compiled with System V SHM support
loading driver ..

starting engine
cannot set thread to real-time priority (FIFO/10) (1: Operation not
permitted)
cannot set thread to real-time priority (FIFO/20) (1: Operation not
permitted)
**** alsa_pcm: xrun of at least 10.319 msecs
I'm very sorry if the message is bit lengthy, but I wanted to give all
the info that I think is needed. Any tip or hint appreciated.
TIA
