Re: [Gwc-general] Playback speed problems

[Alister H. <ali...@gm...>]

Hi everyone,
I know this conversation is very old, but for the record, I have today
pushed a fix in master (https://github.com/AlisterH/gwc) for mono files
playing at 2x speed when using the pulseaudio backend.  Hopefully this was
the problem Tom encountered, and there isn't a separate issue causing 2x
playback.

I believe all three linux backends (oss, alsa and pulseaudio) are working
reasonably reliably now.

However, I have only tested the pulseaudio backend in Ubuntu on WSL
(Windows Subsystem for Linux), not on an actual Linux system.  If there are
others using the pulseaudio backend I'd appreciate it if they can test this
latest change to make sure it doesn't break anything.

Thanks.
