The first line most certainly does cause the pulseaudio command to run and interpret the remainder of the file. My complaint, poorly worded, is that IT DOESN'T WORK. Here's the full output of running that script: [dad@datbird ~]$ ./pulsestart ALSA lib pcm_hw.c:1207:(_snd_pcm_hw_open) Invalid value for card E: module-alsa-sink.c: Error opening PCM device plughw:0,0: No such device E: module.c: Failed to load module "module-alsa-sink" (argument: "device=plughw:0,0 rate=48000 sink_name=output"): initialization failed. E: module-combine.c: Invalid master sink 'output' E: module.c: Failed to load module "module-combine" (argument: "master=output slaves=output2 sink_name=combined"): initialization failed. E: main.c: No sink by that name. ALSA lib pcm_hw.c:1207:(_snd_pcm_hw_open) Invalid value for card E: module-alsa-sink.c: Error opening PCM device plughw:0,0: No such device E: module.c: Failed to load module "module-alsa-sink" (argument: "device=plughw:0,0 rate=48000 sink_name=output"): initialization failed. E: module-combine.c: Invalid master sink 'output' E: module.c: Failed to load module "module-combine" (argument: "master=output slaves=output2 sink_name=combined"): initialization failed. E: main.c: daemon/main.c : Fatal error. Default sink name (combined) does not exist in name register. So this script, advertised as the way to achieve a "sensible Pulseaudio configuration", fails to do so. The initial error suggests that my system is lacking a "PCM device plughw:0,0". That may be true, but I have no clue why, or how to remedy that omission. What, exactly, is a "PCM device plughw:0,0"? How I long for the good old days when Brian Kernighan could accurately say "Everything in the UNIX system is a file". I've spent several days trying without success to start the pulseaudio daemon. No amount of googling has given me a clue how to defeat these error messages. So, without submitting to the gnome monster, I have no sound. This is certainly a showstopper for me and is blocking any further Fedora 8 installations. Suggestions how to start the pulseaudio daemon outside of gnome are most welcome, especially those tested and verified to work. -- David A. De Graaf DATIX, Inc.
