The relevant stuff is: Oct 29 23:52:11 draal kernel: ALSA dsp_spos_scb_lib.c:1188: dsp_spos: creating SRC "SrcTask_SCB0" Oct 29 23:52:11 draal kernel: ALSA dsp_spos_scb_lib.c:295: dsp_spos: creating SCB <SrcTask_SCB0> Oct 29 23:52:11 draal kernel: ALSA dsp_spos_scb_lib.c:1355: dsp_spos: setting SRC rate to 44100 Oct 29 23:52:11 draal kernel: ALSA dsp_spos_scb_lib.c:1211: dsp_spos: creating PCM "PCMReader_SCB0" (1) Oct 29 23:52:11 draal kernel: ALSA dsp_spos_scb_lib.c:295: dsp_spos: creating SCB <PCMReader_SCB0> Oct 29 23:52:11 draal kernel: ALSA dsp_spos_scb_lib.c:1355: dsp_spos: setting SRC rate to 11025 Oct 29 23:52:21 draal kernel: ALSA dsp_spos_scb_lib.c:231: cs46xx_dsp_proc_free_scb_desc: freeing PCMReader_SCB0 Oct 29 23:52:21 draal kernel: ALSA dsp_spos_scb_lib.c:231: cs46xx_dsp_proc_free_scb_desc: freeing SrcTask_SCB0 Why does it set 44.1kHz first and then set it to 11kHz? I hear the first piece (frag?) of the sample played repeatedly, as if it were not servicing interrupts... Messages for the 2nd pcm channel are identical if you s/(1)/(2)/ above. As to the recording problem, I have tried all the options I can think of, all the mixer settings and possible inputs, and I still get ticking. NO messages are written to the logs during the record. arecord -d 2 -f cd blah.wav I have placed this file here: http://mcelrath.org/blah.wav.bz2 Cheers, -- Bob Bob McElrath Univ. of Wisconsin at Madison, Department of Physics "The surest way to corrupt a youth is to instruct him to hold in higher esteem those who think alike than those who think differently." -- Nietzsche
