Re: [Gwc-general] sound only in little bursts

Thanks for the reply, Jeff.
I put in debugging to look at the value returned by 
audio_device_processed_bytes()
when called from set_playback_cursor_position(). I get output like this:

audio_device_processed_bytes: 16432
play_a_block: bytes_left 1454776
leaving start with audio_playback=1
audio_device_processed_bytes: 22528
audio_device_processed_bytes: 29552
play_a_block: bytes_left 1441656
audio_device_processed_bytes: 31520
audio_device_processed_bytes: 40512
audio_device_processed_bytes: 28864
play_a_block: bytes_left 1442344
audio_device_processed_bytes: 33136
audio_device_processed_bytes: 40960
audio_device_processed_bytes: 40960
play_a_block: bytes_left 1430248
audio_device_processed_bytes: 40960
audio_device_processed_bytes: 40960
audio_device_processed_bytes: 40960
play_a_block: bytes_left 1430248

Curiously, the number that it freezes at is always 40960. What's the 
magic in 40960, I wonder? It's not even divisible by 42. ;-)
