Hi,
In my previous post I referred to an error message given by xmms (w/
alsa-xmms plugin). Since then I set up mplayer and when I started to play
a divx file the exact same error came up. Here's the output of both:
hobbz@graviton:~$ xmms
xmms: simple.c:1376: snd_mixer_selem_get_playback_volume: Assertion

There are two simple.c files under alsa-lib/. The one this refers to is
src/mixer/simple.c. I've noted line 1376 below.
int snd_mixer_selem_get_playback_volume(snd_mixer_elem_t *elem,
snd_mixer_selem_channel_id_t channel, long *value)
{
selem_t *s;
assert(elem);
assert(elem->type == SND_MIXER_ELEM_SIMPLE);
s = elem->private_data;
assert((unsigned int) channel < s->str[PLAY].channels); /* Line 1376 */
assert(s->caps & (CAP_PVOLUME|CAP_GVOLUME));
if (s->caps & CAP_PVOLUME_JOIN)
channel = 0;
*value = s->str[PLAY].vol[channel];
return 0;
}
I'm using a Soundblaster Extigy and the snd-usb-audio driver from
alsa-drivers.
I just installed the alsa drivers, libs, and utils on my roommate's
machine with no problem. The only real difference between our setups is
that he has an SB Live! Platinum. So I think the error must originate
somewhere in the usb code or the way the data is being returned by the
kernel driver. Then again, I'm still just a squire when it comes to
coding.
Anyone have any insight?
Regards,
Josh Hattery
