I've been using the newpcm drivers for some time, and they seem to work with
most things, but I've noticed some problems, specifically with the
RealPlayer 7 Beta for linux. The sound seems to jump at the beginning of a
stream, leaving it at least 3-4 seconds behind the counter and any video
content. This makes video streams hard to watch, and also cuts off local
streams early. Also, on remote streams, the sound clicks and squeals loudly
about 1-2 seconds into the stream, and the stream stays out of sync with the
RealPlayer counter the whole time. I have a PR open on this, misc/18728.
All of this seems to have started happening around the time of the May 12
MFC, it looks like. I don't know enough about how newpcm works to be able to
offer any advice on fixing the code, but I'd be willing to take a look at it
in my spare time, and I can try any patches someone can come up with. I have
my dmesg pasted below; this is from -STABLE CVSupped Sunday night.
