Likewise gwc which uses the OSS interface.

It seems the latest xmms source uses 'S16_NE' (which is S16_BE on big-endian platforms) as the pcm format, which works correctly. alsa-tools/acdec/output.c also has a problem.. it uses S16_LE on big-endian platforms. I am able to successfully open the SPDIF output and output *something* with a commandline like: ac3dec -D hw:0,0 -C THX.ac3 However, the hardware decoder (yamaha receiver) is getting garbled data and plays what sounds like stacatto static. ac3dec -C THX.ac3 gives the following: Using PCM device 'iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2' ALSA lib pcm_hw.c:292:(snd_pcm_hw_hw_params) SNDRV_PCM_IOCTL_HW_PARAMS failed: No such device or address PCM hw_params failed: No such device or address Output open failed Another interesting bit...
