It's a bug, of course, though. Anyway, PLEASE open another bug. This is out of the topic of this thread -- "aplay/arecord cannot play/capture A_LAW". And please show the ALSA version you're using. I cannot see the relevant assert line found in the message. ---------------------------------------------------------------------- Raymond - 04-25-06 02:59 ---------------------------------------------------------------------- au88xx driver also support A-Law and MU-LAW. aplay -v -f A_LAW -Dossdriver test.raw Playing raw data 'test.raw' : A-Law, Rate 8000 Hz, Mono aplay: set_params:901: Sample format non available pcm.alawoss { type alaw slave { pcm ossdriver format S16_LE } } aplay -v -f A_LAW -Dalawoss test.raw Playing raw data 'test.raw' : A-Law, Rate 8000 Hz, Mono A-Law conversion PCM (S16_LE) Its setup is: stream : PLAYBACK access : RW_INTERLEAVED format : A_LAW subformat : STD channels : 1 rate : 8000 exact rate : 8000 (8000/1) msbits : 8 buffer_size : 4096 period_size : 1024 period_time : 128000 tick_time : 0 tstamp_mode : NONE period_step : 1 sleep_min : 0 avail_min : 1024 xfer_align : 1024 start_threshold : 4096 stop_threshold : 4096 silence_threshold: 0 silence_size : 0 boundary : 1073741824 Slave: ALSA <-> OSS PCM I/O Plugin Its setup is: stream : PLAYBACK access : MMAP_INTERLEAVED format : S16_LE subformat : STD channels : 1 rate : 8000 exact rate : 8000 (8000/1) msbits : 16 buffer_size : 4096 period_size : 1024 period_time : 128000 tick_time : 0 tstamp_mode : NONE period_step : 1 sleep_min : 0 avail_min : 1024 xfer_align : 1024 start_threshold : 4096 stop_threshold : 4096 silence_threshold: 0 silence_size : 0 boundary : 1073741824 Issue History Date Modified Username Field Change ====================================================================== 04-01-06 04:26 Raymond New Issue 04-03-06 07:16 Raymond Note Added: 0009085 04-03-06 07:36 Raymond Note Added: 0009086 04-07-06 19:32 tiwai Note Added: 0009152 04-08-06 07:47 Raymond Note Added: 0009171 04-10-06 16:52 tiwai Note Added: 0009199 04-11-06 07:46 Raymond Note Added: 0009229 04-11-06 07:55 Raymond Note Edited: 0009229 04-11-06 09:41 Raymond Note Edited: 0009229 04-20-06 15:29 tiwai Status new => resolved 04-20-06 15:29 tiwai Resolution open => not an issue 04-20-06 15:29 tiwai Assigned To => tiwai 04-20-06 15:29 tiwai Note Added: 0009384 04-24-06 15:07 Raymond Status resolved => feedback 04-24-06 15:07 Raymond Resolution not an issue => reopened 04-24-06 15:07 Raymond Note Added: 0009451 04-24-06 15:48 tiwai Status feedback => resolved 04-24-06 15:48 tiwai Resolution reopened => not an issue 04-24-06 15:48 tiwai Note Added: 0009453 04-24-06 16:43 Raymond Status resolved => feedback 04-24-06 16:43 Raymond Resolution not an issue => reopened 04-24-06 16:43 Raymond Note Added: 0009468 04-24-06 16:50 tiwai Status feedback => resolved 04-24-06 16:50 tiwai Resolution reopened => not an issue 04-24-06 16:50 tiwai Note Added: 0009472 04-25-06 02:59 Raymond Status resolved => feedback 04-25-06 02:59 Raymond Resolution not an issue => reopened 04-25-06 02:59 Raymond Note Added: 0009483 ====================================================================== ------------------------------------------------------- Using Tomcat but need to do more?
