The outputs are all the same between 0.6 and 0.7, but I guess you knew that. So I tried 0.5 and it gave the same results, I don't think there is anyone arguing that 0.5 sounds different to 0.6 and 0.7, so must be down to something else. Is there any way to stop the usb pid from changing priority to 59 ? I would prefer to have control over what priority I have processes running at. cheers 0.5 # /etc/init.d/squeezeplay restart Stopping SqueezePlay rm: can't remove '/var/run/squeezeplay.wdog': No such file or directory Starting SqueezePlay # Squeezeplay 7.7.2 r9663 ALSA lib pcm.c:2202:(snd_pcm_open_noupdate) Unknown PCM disabled 20120612 20:30:44.121 ERROR pcm_test:830 Playback open error: No such file or directory 20120612 20:30:44.615 DEBUG pcm_test:852 max sample rate 192000 20120612 20:30:44.616 DEBUG audio_thread_execute:879 audio_thread_execute 20120612 20:30:44.619 INFO _pcm_open:663 Opened device hw:CARD=M192kHz using format: S32_LE pid 305's current scheduling policy: SCHED_FIFO pid 305's current scheduling priority: 95 pid 305's new scheduling policy: SCHED_FIFO pid 305's new scheduling priority: 59 Hardware PCM card 1 'Musical Fidelity V-Link 192kHz' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : MMAP_INTERLEAVED format : S32_LE subformat : STD channels : 2 rate : 44100 exact rate : 44100 (44100/1) msbits : 32 buffer_size : 131072 period_size : 2048 period_time : 46439 tstamp_mode : NONE period_step : 1 avail_min : 2048 period_event : 0 start_threshold : 1 stop_threshold : 131072 silence_threshold: 0 silence_size : 0 boundary : 1073741824 20120612 20:30:52.294 DEBUG playback_callback:550 playback started, copyright not asserted 0.6 # /etc/init.d/squeezeplay restart Stopping SqueezePlay rm: can't remove '/var/run/squeezeplay.wdog': No such file or directory Starting SqueezePlay # Squeezeplay 7.7.2 r9663 ALSA lib pcm.c:2202:(snd_pcm_open_noupdate) Unknown PCM disabled 20120612 20:04:43.758 ERROR pcm_test:880 Playback open error: No such file or directory 20120612 20:04:44.246 DEBUG pcm_test:902 max sample rate 192000 20120612 20:04:44.248 DEBUG audio_thread_execute:931 audio_thread_execute 20120612 20:04:44.251 INFO _pcm_open:720 Opened device hw:CARD=M192kHz using format: S32_LE sample rate: 44100 pid 305's current scheduling policy: SCHED_FIFO pid 305's current scheduling priority: 95 pid 305's new scheduling policy: SCHED_FIFO pid 305's new scheduling priority: 59 Hardware PCM card 1 'Musical Fidelity V-Link 192kHz' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : MMAP_INTERLEAVED format : S32_LE subformat : STD channels : 2 rate : 44100 exact rate : 44100 (44100/1) msbits : 32 buffer_size : 131072 period_size : 2048 period_time : 46439 tstamp_mode : NONE period_step : 1 avail_min : 2048 period_event : 0 start_threshold : 1 stop_threshold : 131072 silence_threshold: 0 silence_size : 0 boundary : 1073741824 20120612 20:04:50.298 DEBUG playback_callback:553 playback started, copyright not asserted 0.7 # /etc/init.d/squeezeplay restart Stopping SqueezePlay rm: can't remove '/var/run/squeezeplay.wdog': No such file or directory Starting SqueezePlay # Squeezeplay 7.7.2 r9663 ALSA lib pcm.c:2202:(snd_pcm_open_noupdate) Unknown PCM disabled 20120612 20:09:54.837 ERROR pcm_test:882 Playback open error: No such file or directory 20120612 20:09:55.332 DEBUG pcm_test:904 max sample rate 192000 20120612 20:09:55.334 DEBUG audio_thread_execute:933 audio_thread_execute 20120612 20:09:55.337 INFO _pcm_open:722 Opened device hw:CARD=M192kHz using format: S32_LE sample rate: 44100 pid 305's current scheduling policy: SCHED_FIFO pid 305's current scheduling priority: 95 pid 305's new scheduling policy: SCHED_FIFO pid 305's new scheduling priority: 59 Hardware PCM card 1 'Musical Fidelity V-Link 192kHz' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : MMAP_INTERLEAVED format : S32_LE subformat : STD channels : 2 rate : 44100 exact rate : 44100 (44100/1) msbits : 32 buffer_size : 131072 period_size : 2048 period_time : 46439 tstamp_mode : NONE period_step : 1 avail_min : 2048 period_event : 0 start_threshold : 1 stop_threshold : 131072 silence_threshold: 0 silence_size : 0 boundary : 1073741824 20120612 20:10:03.824 DEBUG playback_callback:553 playback started, copyright not asserted ------------------------------------------------------------------------ SBGK's Profile: http://forums.slimdevices.com/member.php?userid=52003 View this thread: http://forums.slimdevices.com/showthread.php?t=94855 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
