alsa-project/alsa-lib pull request #115 was opened from perexg:
It seems that the commit "pcm: ioplug: Transfer all available data" introduced new regressions (wrong memory access). The second issue is that the avail_update in ioplug does not move appl_ptr nor hw_ptr, so it's possible that the transfers may be repetitive.
This patch moves the transfer calls to mmap_begin callback where it should be. The pointer wraps are handled by design now.
