[alsa-devel] em8300 and ALSA problems

[Jan Willies]

Hi,

I really want pulseaudio badly and since it doesn't work very good with OSS output, I decided to switch to ALSA. However, I'm running into some problems with ALSA. My dxr3 (em8300) card seems to be detected by ALSA (/proc/asound/cards lists it too): 

[root at server ~]# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: I82801BAICH2 [Intel 82801BA-ICH2], device 0: Intel ICH [Intel 82801BA-ICH2]

card 1: EM8300 [Sigma Designs' EM8300], device 1: EM8300/1 [EM8300 IEC958]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

But for some reason it won't play anything:

I don't really have a clue what's going on. People on #alsa didn't either. Here's a link to tsalsa output: http://nopaste.com/p/a0NYa75gW

The module was loaded with options em8300 dicom_fix=1 dicom_control=1 dicom_other_pal=1 audio_driver=alsa. I'm running em8300-0.16.4-rc1
