OK, I tried playing the stereo file but still getting the same error: deathu@vader:~/Desktop$ aplay -D hw:1 testtone192.wav Playing WAVE 'testtone192.wav' : Signed 16 bit Little Endian, Rate 192000 Hz, Stereo aplay: set_params:918: Sample format non available
Oops, the device supports only 24-bit samples, and this isn't supported by .wav files, so using hw:1 won't ever work with aply.
Well, my test file contained a single constant frequency tone; it is still there while I play the 192k file through plughw:1,0, but burried under:
- periodic series of clicks
- other high frequency tones
Here is /proc/asound/card1/stream0 while playing through plughw:1,0: ... Momentary freq = 192000 Hz (0x18.0000)
Does this value ever change? Could you again try inserting a printk to see whether the driver thinks it gets invalid frequency values?
