PC Setup:

PC(6870 HDMI Output) to Receiver(Pioneer VSX HDMI Input) to TV(Panasonic TH-P42U20Z)

Using Catalyst 13.1

Whenever the audio playback is disrupted in anyway (eg. changing a song manually in Foobar2K, or even pausing and resuming playback), there is a 1-second gap before the sound is outputted on the speakers.

This problem also affects playback of movies when the seekbar is clicked to a different location or when playback is paused and resumed.

This issue is not present in the Realtek R270 HDMI driver.

I have tried all output options, including DS(DirectSound), WASAPI(Event), and WASAPI(Push).

Please advise me if this is a known issue, and whether a quickfix is possible.

I am happy to provide any further information.

Thank you.
