This is just my ignorance I imagine. I have ALSA installed as part of
my kernel 2.6.15.4, ALSA is 1.0.10rc3. Machine is an EPIA mini-ITX
MII6000E (VIA8233) (slackware 10.2):
When I play something with mpg321 -o alsa, or even without the "-o alsa"
I get the underruns message and the sound is choppy. So I searched on
Google and came up with this to put in the asound.conf:
pcm.anyshit {
type dmix
ipc_key 1234
slave {
pcm ?hw:0,0?
#period_time 0
#period_size 1024
## ? vR ? 2005-02-13 : lowered this from 4096 to 1024 to
get rid of
## skipping and ?ALSA: underrun, at least 0ms.? errors
#buffer_size 4096 # buffer size < 6653, but pow(x, 2)
#buffer_time 84000
#rate 44100 # we want to play CDs only
}
}
That's wrong your thinking, it should have " where it has ? and indeed
when I run mpg321 I get
ALSA lib conf.c:1578:(snd_config_load1) _toplevel_:15:0:Unexpected char
ALSA lib conf.c:2823:(snd_config_hook_load) /etc/asound.conf may be old
or corrupted: consider to remove or fix it
ALSA lib conf.c:2686:(snd_config_hooks_call) function
snd_config_hook_load returned error: Invalid argument
ALSA lib conf.c:3052:(snd_config_update_r) hooks failed, removing
configuration
But it plays perfectly. If Ichange the ? to " in the pcm ?hw:0,0? line,
then the errors go away but the sound is choppy again.
I have not modified any of the stuff in /usr/share/alsa. Any ideas?
