This sounds like buffer underruns when listening to live radio. When
cAudioRepacker is enabled and with the recent ringbuffer patch, you'll
get each audio frame (~ 24 ms) as soon as it is available.

If the output device starts immediately with playback, it is likely that
there are buffer underruns, especially when xine drops some audio frames
when syncing.

I don't know whether xineliboutput has some setup options to control
buffering in live mode. In vdr-xine's setup page you can specify an
initial buffer size (e. g. 4 video frames ~ 160 ms) which must first be
established before replaying at normal speed starts.

BTW: The software decoding solutions need such a buffer to compensate
latency issues with the threads involved in the chain from input to output.

Bye.
