(Get the code!)
Thanks Chris. Is that easily reproducible for you? Using a particular video, or did you try with more than one?
There are probably some other cases where we could hit this problem. If there's not enough audio available in the decoded frames when we try to resume playback we won't be able to hit the prebuf limit that resumes playback.
Maybe we should call snd_pcm_start in sa_stream_write so that playback always begins as soon as we've written some audio data, or shrink the prebuf size significantly. The former would make the behaviour match the Mac backend, and the latter would match the Win32 backend where the "prebuf" buffer size is fixed at 1024 bytes (around 5-6ms of audio). What we really want is the behaviour of all of the backends to match as much as possible, but that's a bigger project.
