[Alsa-user] FW: Ice 1712 problems

Title: FW: Ice 1712 problems

Hi all,



  Here is my problem.  I have set up a Delta 44 (ice1712) soundcard.  It is functioning, but I am having great difficulty in setting up the ability to record or play from multiple pairs of channels at the same time.  I also am having a hard time playing directly to the hw:0,0 device.  I am however able to use plughw:0,0.



[EMAIL PROTECTED] ~]# aplay test.wav

Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Aborted by signal Interrupt...





[EMAIL PROTECTED] ~]# aplay -D hw:0,0 test.wav Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

aplay: set_params:896: Sample format non available



[EMAIL PROTECTED] ~]# arecord -D ch12 test.wav ALSA lib pcm_dshare.c:613:(snd_pcm_dshare_open) The dshare plugin supports only playback stream

arecord: main:544: audio open error: Invalid argument



 [EMAIL PROTECTED] ~]# arecord -D hw:0,0 test.wav Recording WAVE 'test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono

arecord: set_params:896: Sample format non available







Following is my asound.conf file.  I have checked sing aplay and arecord with the -l flag, and the conf file is being used.





pcm_slave.delta {

  pcm "hw:0,0"

  channels 4

  rate 44100

  buffer_size 4096

  period_size 2048

  periods 0

  period_time 0

}



pcm.ch12 {

  type dshare

  ipc_key 47110815

  slave delta

  bindings.0 0

  bindings.1 1

}



pcm.ch34 {

  type dshare

  ipc_key 47110815

  slave delta

  bindings.0 2

  bindings.1 3

}





I have also tried using the pcm as "plughw:0,0". 





[EMAIL PROTECTED] ~]# aplay -D ch12 test.wav ALSA lib pcm_dshare.c:687:(snd_pcm_dshare_open) dshare plugin can be only connected to hw plugin Segmentation fault



Any help would be greatly appreciated.



Thanks,



Bobby
