Hey Hika,

After re-reading the forum post again, I still don't believe we are
talking about the same issue.

In my case, audio and video playback stops (I think) because there is
not yet enough recorded (video) buffer for playback to start. If I
pause for a second or two and then resume playback, audio and video
are both perfectly normal.

As the ivtv driver is only initialised once when the LiveTV session
starts, and I do not experience tinny audio or missing audio, the ivtv
driver seems to be working just fine. The symptoms described in the
forum post suggest that video would be recorded normally but audio
would be tinny or missing altogether.

Scheduled recordings are also perfect (just watched the latest UK
Blacklist episode, recorded a few hours ago, without any issues at
all).

Cheers,
Nick
