[Openvortex-dev] Click bug.

[Manuel Jander]

Hi,

I have been investigating the click bug.

I observed that it happens when the bitrate is low and there are
few periods being used. That may explain why it goes away when
increasing the buffer size (more periods).

The clicks happen at exactly (period size)*(period count) intervals,
starting at 0. The clicks when observed looking at the waveform that was
playback (recorded in a loop) semes like there are some samples (could
be only one) missing.

I checked at the values returned form " snd_vortex_pcm_pointer()" ALSA
callback, and they seme OK.
It doesnt matter if less that 4 periods are used (not using the buffer
shifter).

Some ideas:
-Maybe the FIFO is flushed accidentally ?
-The upper layer write to early into  astill playing buffer ?

Best Regards

Manuel Jander.
