In my main loop I use SNDCTL_DSP_GETOSPACE to poll

that all
fragments practically stay free.
Did you think about using select to check for free space in your
device instead of this GETOSPACE method?
The polling is not a good way to do it, I think.
Maybe you also have the card in non-blocking mode (or the opposite).
If you change that, myabe also...
Try to avoid the polling method, IMHO.
Take care,
