hey,
using alsa 1.0.0pre1
picked up a Hercules DigiFire 7.1 card today. CS46xx based.
i only have an optical s/pdif cable in the card going to my amp
normal stuff works fine (using the oss compat module). i get
nice clean sound. but what i really want to do is play dvds
w/ ogle and get the surround sound single to my amp.
but ogle fails to configure the device correctly. the ogle
code is at the bottom of the email. it fails on the call to
"snd_ctl_elem_write". the snd_pcm_info_get_device(info) and
snd_pcm_info_get_subdevice(info) are returning the correct
values (device 2, sub device 0). just can't seem to update
the IEC958 control.
here is the output of iecset:
[EMAIL PROTECTED] alsa-utils-1.0.0pre1]# ./iecset/iecset
Mode: consumer
Data: audio
Rate: 48000 Hz
Copyright: protected
Emphasis: none
Category: PCM coder
Original: original
Clock: 1000 ppm
i then ran iecset -x and copied that output into the config
of ogle. still no go.
what am i doing wrong?
thanks
henri
