My audio driver supports buffer sizes from 128 to 32768 and period sizes from 8 to 2048. I am trying to set the period size as 1030 (just a random number between 8 & 2048, but not multiple of 2^n) and buffer size as 16*buffer_size (i.e. 16480). The output is as follows:
Buffer size range from 128 to 32768 Period size range from 8 to 2048 Request period size 1030 and got 1030 Plug PCM: Hardware PCM card 0 'TWL4030' 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 : 16480 period_size : 1030 period_time : 23356 tstamp_mode : NONE period_step : 1 avail_min : 1030 start_threshold : 16480 stop_threshold : 16480 silence_threshold: 0 silence_size : 0 boundary : 1080033280
The problem with this setup is the application just hangs without playing anything. If I use period size as 2048, the app plays the song but clips the last part of it. If I use 1024/512, it works fine.
I have tried alsa lib version 1.0.15 & 1.0.16 but the problem persists. Is there anything wrong with my app or audio driver?
Please help.
Thanks in advance, Anuj Aggarwal
