Well, here is something to try out. I'll fix something more appropriate (git-send-email, debdiff, etc) in the next few days, right now I'm a bit to tired for the formalities. But I hope these three fixes should improve the situation.
1) + /* Prevent accidental overrun of the fake ringbuffer */ + if (size >= pcm->buffer_attr.tlength) + size = pcm->buffer_attr.tlength-1; This cured a hang I could sometimes reproduce while recovering from an xrun. 2) + writebytes = size * pcm->frame_size; + ret = pa_stream_write(pcm->stream, buf, writebytes, NULL, 0, 0); + pcm->last_size -= writebytes; This updates the hw_ptr variable correctly, which fixed some continous xruns for me as well as reduced CPU usage. 3) + /* Reset faked buffer */ + pcm->last_size = 0; + pcm->ptr = 0; + update_ptr(pcm); Before prepare is called the ioplug interface resets its pointers, so we should do the same. No real difference in experience from this one, it just seems reasonable. ** Attachment added: "Apply this patch to Lucid's alsa-plugin/pulse/pcm_pulse.c" http://launchpadlibrarian.net/37602904/pcm_pulse.patch -- Applications routed through the pulse pcm alsa-plugin crackle/die quickly https://bugs.launchpad.net/bugs/485488 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
