Hello, I have a problem in starting pulseaudio with my EMU-0404USB after a recent upgrade from Fedora9 to Fedora10. It seems that pulseaudio cannot set some hw parameters to my card as follows.  It fails to startup with default configuration which uses HAL so I override the <a href="http://default.pa">default.pa</a> config file to force a load of module-alsa-sink with plughw:0,0.  However it doesn't help. $ pulseaudio I: caps.c: Limited capabilities successfully to CAP_SYS_NICE. I: caps.c: Dropping root privileges. I: caps.c: Limited capabilities successfully to CAP_SYS_NICE. E: alsa-util.c: Failed to set hardware parameters on plughw:0,0: Operation not permitted E: module.c: Failed to load  module "module-alsa-sink" (argument: "device=plughw:0,0"): initialization failed. E: main.c: Module load failed. E: main.c: Failed to initialize daemon. However the same device (plughw:0,0) works fine when I use aplay.  Any clues?  Thanks! $ aplay -v -D plughw:0,0 Track01.wav Playing WAVE 'Track01.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Plug PCM: Linear conversion PCM (S24_3LE) Its setup is:   stream       : PLAYBACK   access       : RW_INTERLEAVED   format       : S16_LE   subformat    : STD   channels     : 2   rate         : 44100   exact rate   : 44100 (44100/1)   msbits       : 16   buffer_size  : 22050   period_size  : 5513   period_time  : 125011   tstamp_mode  : NONE   period_step  : 1   avail_min    : 5513   period_event : 0   start_threshold  : 22050   stop_threshold   : 22050   silence_threshold: 0   silence_size : 0   boundary     : 6206523236469964800 Slave: Hardware PCM card 0 'E-MU 0404 | USB' device 0 subdevice 0 Its setup is:   stream       : PLAYBACK   access       : MMAP_INTERLEAVED   format       : S24_3LE   subformat    : STD   channels     : 2   rate         : 44100   exact rate   : 44100 (44100/1)   msbits       : 24   buffer_size  : 22050   period_size  : 5513   period_time  : 125011   tstamp_mode  : NONE   period_step  : 1   avail_min    : 5513   period_event : 0   start_threshold  : 22050   stop_threshold   : 22050   silence_threshold: 0   silence_size : 0   boundary     : 6206523236469964800 Cheers, Kaworu
