hello, I've read everything I could find for this device: http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=Midiman%2… and http://alsa.cvs.sourceforge.net/*checkout*/alsa/alsa-kernel/Documentation/A… After following all instructions in the first file, and trying aplay as stated in the second file with device_setup 0x01, I get this: thesamo@blinken ~ $ aplay -D hw:1,0 -c2 -t raw -r48000 -fS16_BE ed.raw Playing raw data 'ed.raw' : Signed 16 bit Big Endian, Rate 48000 Hz, Stereo aplay: set_params:962: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_BE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: 48000 PERIOD_TIME: 125000 PERIOD_SIZE: 6000 PERIOD_BYTES: 24000 PERIODS: 4 BUFFER_TIME: 500000 BUFFER_SIZE: 24000 BUFFER_BYTES: 96000 TICK_TIME: 1000 I tried different device setups and bit-depths but it always comes down to the same error. Any help is appreciated. Thanks in advance :) -- theSamo <thesamo(a)gmail.com>
