ok. seems my local tree hasn't been following the changes at kernel inclusion. i'm really sorry. unfortunately the bug remains, it only manifests differently. after initializing the ice (cap + play are linked): [~] cat /proc/asound/ice/pcm0p/sub0/hw_params access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 10 rate: 44100 (44100/1) period_size: 128 buffer_size: 256 tick_time: 10000 [~] cat /proc/asound/ice/pcm0p/sub0/sw_params tstamp_mode: NONE period_step: 1 sleep_min: 0 avail_min: 128 xfer_align: 128 start_threshold: 4294967295 stop_threshold: 256 silence_threshold: 0 silence_size: 0 boundary: 1073741824 [~] cat /proc/asound/ice/pcm0p/sub0/status state: PREPARED trigger_time: 0.000000 tstamp : 1023125218.959946 delay : 36548963 avail : 0 avail_max : 0 ----- hw_ptr : 0 appl_ptr : 256 calling snd_pcm_close() takes a few seconds during which i see this: [~] cat /proc/asound/ice/pcm0p/sub0/status state: DRAINING trigger_time: 1023125380.999721 tstamp : 1023125381.905192 delay : -39746 avail : 40002 avail_max : 40002 ----- hw_ptr : 40002 appl_ptr : 256 a little later while still in ioctl() -- [~] cat /proc/asound/ice/pcm0p/sub0/status state: DRAINING trigger_time: 1023125380.999721 tstamp : 1023125383.741754 delay : -120739 avail : 120995 avail_max : 120995 ----- hw_ptr : 120995 appl_ptr : 256 etc etc; then alsa_error_handler reports: pcm_hw.c:413 (snd_pcm_hw_drain): SNDRV_PCM_IOCTL_DRAIN failed, err = Input/output error and printk says: Jun 3 19:29:51 localhost kernel: ALSA ../alsa-kernel/core/pcm_native.c:1093: playback drain error (DMA or IRQ trouble?) and the application then exits normally. the same setup with stop_threshold = ~0 behaves the same (same printk, too), only the alsa_error_handler message reads: pcm_hw.c:276 (snd_pcm_hw_hw_free): SNDRV_PCM_IOCTL_HW_FREE failed, err = File descriptor in bad state i did both tests (with the different stop_threshold values) with the emu8k. it shows exactly the same symptoms: running hw_ptr, delay and avail, same alsa_error_handler and printk messages. tim _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
