--- Comment #29 from rkfg <[email protected]> --- I've found that 16000 buffer time with 4000 period time doesn't underrun while if I change the period time to 1000 or 2000 it underruns pretty quickly. Lower buffer times underrun regardless of the period time it seems. 16000/4000 shows these params: > aplay -D hw:0,0 -v --buffer-time=16000 --period-time=4000 /tmp/fr025.wav Playing WAVE '/tmp/fr025.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Hardware PCM card 0 'HDA Intel PCH' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : RW_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 44100 exact rate : 44100 (44100/1) msbits : 16 buffer_size : 768 period_size : 192 period_time : 4353 tstamp_mode : NONE period_step : 1 avail_min : 192 period_event : 0 start_threshold : 768 stop_threshold : 768 silence_threshold: 0 silence_size : 0 boundary : 6917529027641081856 appl_ptr : 0 hw_ptr : 0 16000/2000 is like this: > aplay -D hw:0,0 -v --buffer-time=16000 --period-time=2000 /tmp/fr025.wav Playing WAVE '/tmp/fr025.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Hardware PCM card 0 'HDA Intel PCH' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : RW_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 44100 exact rate : 44100 (44100/1) msbits : 16 buffer_size : 672 period_size : 96 period_time : 2176 tstamp_mode : NONE period_step : 1 avail_min : 96 period_event : 0 start_threshold : 672 stop_threshold : 672 silence_threshold: 0 silence_size : 0 boundary : 6052837899185946624 appl_ptr : 0 hw_ptr : 0 underrun!!!
