[mythtv-users] frontend freeze on "audio waiting for space on soundcard"

[Mike Choy]

To reply to myself

It does look like the "audio waiting for space on sound card" is normal
as I have just checked my second mythbox which does not exhibit the freeze
looks like I need to try a different tact on trying to locate the
frontend freeze issue.
