I've been trying to get mplayer to work with my delta44. I have a working plug pcm type: pcm.dplug { type plug slave.pcm ice1712 } and $ mplayer -ao alsa9:dplug foo.avi will play audio, but no more than a few frames of video. If I look at the verbose output I see; alsa-init: requested format: 48000 Hz, 2 channels, Signed 16-bit (Little-Endian) alsa-init: compiled for ALSA-0.9.4 alsa-init: soundcard set to dplug alsa-init: pcm opend in block-mode alsa-init: chunksize set to 1024 alsa-init: current val=7, fragcount=7 alsa-init: unable to set periods: Invalid argument alsa-init: got buffersize=26212 The number of periods the driver requests is 7 which the code obtains by calling snd_pcm_hw_params_get_periods_max(). So my question is, what should this value be for a plug, should it be the same as the underlying slave. Is the ice1712 not reporting the correct maximum? The maximum jackd will start with is 5 periods so there seems to be something wrong here. --ant
