[mythtv-users] 0.22RC1 HD-PVR SPDIF audio problems

[Ken Bass]

I just configured a HD-PVR.

When I change channels, various channels do not have audio. If I select 
MSNBC for example, I get the following in the logs:

One this condition is hit, changing to other channels result in no 
audio. However, if I exit Watch TV and reenter, the same channel works 
without the above errors reported by the backend.
