---------------------------------------------------------------------- Raymond - 07-06-06 03:51 ---------------------------------------------------------------------- It seem that dmix need the timer and those soundcard does not support hardware mixing only has one playback subdevice and one capture subdevice How about those sound cards which have many playback subdevices and capture subdevices (support hardware mixing) ? Does it mean dmix can also use on the soundcards which have more the one subdevices ? ---------------------------------------------------------------------- bitmage2 - 07-31-06 22:48 ---------------------------------------------------------------------- Card: Sound Fusion CS46xx Chip: Cirrus Logic CS4294 rev 5,Cirrus Logic CS4294 rev 5,Cirrus Logic CS4294 rev 5 As requested in bug 1823, here is the "timer -list" output (WARNING: This is alsa-lib-1.0.12rc1 , running on ALSA driver 1.0.9b): bjork:~/2/root/alsa/alsa-lib-1.0.12rc1/test # ./timer -list Using timer class 1, slave class -1, card 0, device 0, subdevice 0 Timer info: slave = no card = -1 id = 'system' name = 'system timer' average resolution = 4000000 Using 5 tick(s) STATUS: resolution = 4000000 lost = 0 overrun = 0 queue = 0 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 TIMER: resolution = 4000000ns, ticks = 5 STATUS: resolution = 4000000 lost = 0 overrun = 0 queue = 0 Done Issue History Date Modified Username Field Change ====================================================================== 07-05-06 16:14 Raymond New Issue 07-06-06 03:51 Raymond Note Added: 0010850 07-31-06 22:48 bitmage2 Note Added: 0011351 ====================================================================== ------------------------------------------------------------------------- Take Surveys.
