Hello,
I need help to get OSS sound card (driver "sb") working with ALSA.
In my .asoundrc I had defined:
------------
pcm.oss1 {
type oss
device /dev/dsp1
}
ctl.oss1 {
type oss
device /dev/mixer1
}
pcm.sb-es1688 {
type plug
slave {
pcm "pcm.oss1"
rate 8000
channels 1
format U8
# rate 44100
# channels 2
# format "S16_LE"
#Pozn: to rate nutné (funguje alespoň <aplay -D sb-es1688 /usr/share/sounds/alsa/Front_Center.wav>),
#to ostatní pro další (nejde xine, mpg123, ...) nepomáhá
}
}
ctl.sb-es1688 {
type oss
device /dev/mixer1
}
pcm.!default "pcm.sb-es1688"
ctl.!default "ctl.sb-es1688"
----------------------------
The PROBLEM IS:
If I use
aplay -D sb-es1688 /usr/share/sounds/alsa/Front_Center.wav
it works - I can hear, the sound is converted, but if I run
mpg123 -o alsa .....
then
A/ mpg123 seems to playing, but nothing is to hear
B/ an error occur
Playing MPEG stream from girlsjustwanna.mp3 ...
MPEG 1.0 layer III, 128 kbit/s, 44100 Hz joint-stereo
ALSA snd_pcm_hw_params error: Invalid argument
C/ or
ALSA write error: Operation not permitted
D/ ... or something other, or the sound is damaged
[depending what I define in "slave" conversion]
I had thing, that "type plug" with slave will whatever convert to format
defined by "slave" and this format (which is definitely correct for
that card) is send to that card (/dev/dsp1)).
But IT IS NOT SO.
When playing something with mpg123, xine, ... the format is not correct
converted OR /dev/dsp1 is not correct configured.
Can someone tell me, what I do wrong ?
Thank You
