It hung right after outputting "0 - Front Left". I did an strace and the results are included in the file attached. I attempted to vary the sample rate (to 44.1 kHz) with little luck. The wierd thing is that I can execute 'aplay' (with the default device) and get a '.wav' file to play nicely. I can even get a multi-channel (4 to be exact) ".wav" file to go thru 'aplay'. Why speaker-test doesn't work is beyond me. The problem is that I appear to use similar techniques in my own programming as speaker-test, and my program doesen't do that well. Being as how speaker-test IS part of ALSA, I thought I would submit the bug report against it. If other tests need be preformed, I'd be VERY happy to do them. ====================================================================== ---------------------------------------------------------------------- tiwai - 08-03-05 12:18 ---------------------------------------------------------------------- Which version did you use?
