Tanu, Aha, I'm getting closer. I realized that I cannot open the hardware twice. If I do this: load-module module-alsa-sink sink_name=ac3_raw device=spdif:0 load-module module-alsa-sink sink_name=ac3_encode device=a52encode I get an error on the second alsa-sink for a52encode, since ac3_raw already has the device. If I do this: #load-module module-alsa-sink sink_name=ac3_raw device=spdif:0 load-module module-alsa-sink sink_name=ac3_encode device=a52encode The a52encode appears to start: *** Module #0 *** Name: module-alsa-sink Argument: sink_name=ac3_encode device=a52encode Usage counter: n/a Auto unload: no Unfortunately, pulseaudio crashes after pactl list :-( I am having fun though :-) Jim "Jim Duda" <jim at duda.tzo.com> wrote in message news:fq9b8k$s4r$1 at ger.gmane.org... >I think I've learned that in order for a52encode to possibly work, I need to have /var/run/pulse/.asoundrc defined. > > /var/run/pulse/.asoundrc: > > pcm.a52encode { > type a52 > } > > Yields: > > lroom# /usr/bin/pulseaudio --system > E: module-alsa-sink.c: Error opening PCM device a52encode: Device or resource busy > E: module.c: Failed to load module "module-alsa-sink" (argument: "sink_name=ac3_encode device=a52encode rate=48000 > channels=6"): initialization failed. > E: main.c: Module load failed. > E: main.c: failed to initialize daemon. > > If I change a52encode to something else in the .asoundrc, I get: > > E: module-alsa-sink.c: Error opening PCM device a52encode: No such file or directory > E: module.c: Failed to load module "module-alsa-sink" (argument: "sink_name=ac3_encode device=a52encode rate=48000 > channels=6"): initialization failed. > E: main.c: Module load failed. > E: main.c: failed to initialize daemon. > > So, apparently the .asoundrc in /var/run/pulse is recognized. > > Using a52encode:0 results in: > > lroom# /usr/bin/pulseaudio --system > ALSA lib conf.c:3949:(snd_config_expand) Unknown parameters 0 > ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM a52encode:0 > E: module-alsa-sink.c: Error opening PCM device a52encode:0: Invalid argument > E: module.c: Failed to load module "module-alsa-sink" (argument: "sink_name=ac3_encode device=a52encode:0 rate=48000 > channels=6"): initialization failed. > E: main.c: Module load failed. > E: main.c: failed to initialize daemon. > > Some permission problem maybe .... > > Thanks for listening :-) > > Jim > > > "Tanu Kaskinen" <tanuk at iki.fi> wrote in message news:20080229054425.GB12761 at a9a.mannikko1.tontut.fi... >> On Thu, Feb 28, 2008 at 09:36:20PM -0500, Jim Duda wrote: >>> Unfortunately, using a52encode as a device doesn't seem to work.
