At least that's what I think I have. lspci says: 00:08.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall DSP (rev 97) Playback works just fine, and analogue input works as well. With hdspmixer I'm able to route the analogue input to the SPDIF outputs, and I'm able to control the volume of the playback via amixer: [larsi@rocket-sam /tmp]$ amixer cset numid=5 16,8,32768 numid=5,iface=HWDEP,name='Mixer' ; type=INTEGER,access=rw------,values=3,min=0,max=65536,step=1 : values=0,0,0 $ amixer cset numid=5 17,9,32768 (etc) So playback and routing from inputs to outputs works as expected. However, I'm not able to record anything. $ arecord -t raw -r 44100 -c 2 -f S16_LE | od Recording raw data 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo 0000000 000000 000000 000000 000000 000000 000000 000000 000000 * So I'm getting output from the capture device -- but it's all zeroes. I've tried using amixer to route everything to everything else, but that doesn't have any effect for arecord, either. What am I missing? -- (domestic pets only, the antidote for overdose, milk.) larsi@gnus.org * Lars Magne Ingebrigtsen
