use alsamixer. as with all ALSA drivers, after loading, all channels are muted. if there is no state to restore in asound.state or whatever its called, they will stay muted. to make it "simple" to get the volumes up, the driver presents a "simple mixer" interface that alsamixer and other similar programs can use. it controls the gain applied to routing between a playback stream (from the CPU) and an output (to a physical channel). you don't need to know anything about the matrix mixer to use it, but it obviously can't represent the full power of the matrix mixer either. if you pass line_outs_monitor=1, then you should hear all inputs and all outputs in the headphone outs. you don't need to set the mixer to get this to work. i also enclose a very helpful post from a few months back that we should really put into the wiki (below). >As with Jochem's hdsp9652, >cat /proc/asound/card0/pcm0p/sub0/status >shows signs of life (state: RUNNING etc.) please don't confuse your situation with the hdsp9652. there is a bug in the code for the hdsp9652 that prevents any sound regardless of the mixer settings. -- post from roger williams -------------------------------------------- Some of the numbering is discontinuous (because the Multiface doesn't have the Digiface's ADAT2 range of channels), so the full Multiface I/O list is: Inputs to HDSP Mixer ======================================================================== Multiface analogue inputs 1-8 = amixer source channels 0-7 Multiface ADAT inputs 1-8 = amixer source channels 16-23 Multiface SPDIF input = amixer source channels 24-25 alsa_pcm:playback_1-26 = amixer source channels 26-51 Outputs from HDSP Mixer ======================================================================== Multiface analogue outputs 1-8 = amixer destination channels 0-7 Multiface ADAT outputs 1-8 = amixer destination channels 16-23 Multiface SPDIF output = amixer destination channels 24-25 Multiface line (headphone) output = amixer destination channels 26-27 Mapping between Multiface inputs and alsa_pcm:capture channels ======================================================================== Multiface analogue inputs 1-8 = capture_1-8 Multiface ADAT inputs 1-8 = capture_9-16 Multiface SPDIF input = capture_17-18 ------------------------------------------------------- This SF.NET email is sponsored by: eBay Great deals on office technology -- on eBay now!
