It does, but not during playback.
Playback in the way it has to be done on this card is not supported by
hardware and the overflow buffer mechanism is handled by hardware.
Thanks Ralph for all the clarifications and tests with the buffer. I'd
quite like to test a current firmware with a 230k buffer and see whether
this resolves armcrashes after a certain runtime on the taxing channels.
I'm a bit confused as you said you don't have current firmware sources to
build one that'd be compatible with the current drivers. Who's maintaining
the firmware and could there be a chance of experimenting with a 230k
buffer to see whether this is the root cause for instability with DVB-T in
the UK?
