Hi,
I do have an ATI IXP based motherboard and face some issue with ALSA 1.0.12rc1
( same with 1.0.11 ). I must admit that I am using my own linux distro
based on uClibc. I am using 2.6.12.6 linux kernel.
My current issue is faced with the latency test which returns:
Scheduler set to Round Robin with priority 99...
Playback device is hw:0,0
Capture device is hw:0,0
Parameters are 22050Hz, S16_LE, 2 channels, non-blocking mode
Wanted tick time: 0us, poll mode: no
Loop limit is 661500 frames, minimum latency = 64, maximum latency = 4096
Rate doesn't match (requested 22050Hz, get 0Hz)
Unable to set parameters for playback stream: Invalid argument
The rate of the board is set to 0 which cause in some application (like
gstreamer) really bad behavior. The pcm test is working fine unexpectidly !
So I have a global /etc/asound.conf which is configured as:
pcm.rate_convert {
type dmix
ipc_key 1024
slave {
pcm "hw:0,0"
period_size 1024
buffer_size 4096
rate 44100
}
bindings {
0 0
1 1
}
}
pcm.duplex
{
type asym
playback.pcm "dmix"
}
pcm.atiixp {
type plug
slave.pcm "duplex"
}
ctl.atiixp {
type hw
card 0
}
So the dmix entry should be returning 44100 Hz rather than 0.
I am loading alsa with:
/sbin/modprobe snd-atiixp
/sbin/modprobe snd-pcm-oss
/sbin/modprobe snd-mixer-oss
/sbin/modprobe snd-seq-oss
and
/etc/modules.conf contains
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-atiixp
# module options should go here
# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
I will really appreciate help on this !!
