[Ekiga-list] PTLIB alsa plugin status

[Alec Leamas <leamas alec gmail com>]

I  made a short review of the read/write code in the PTLIB alsa plugin 
yesterday. In short:

- Playback and record thread are synchronized in a way that forces the 
two  streams to wait for each others I/O operations.
- There is no rebuffering support. This means data underruns sounds 
worse than necessary.
- Various minor remarks.

I've filed a bug against ekiga with some more details :  
http://bugzilla.gnome.org/show_bug.cgi?id=572953 (pls don't file a bug 
on the formatting of the attachment...).

In my opinion, it's not really worth to put much work on using the 
current alsa plugin. As long as it works, don't touch it... until it 
get's fixed in a proper way, possibly by using a pulse plugin instead.

As for the latency discussion about alsa vs pulse: This review shows 
that anything will be much better than current alsa code...
