Hello,

i have upgraded my 4.x progdvb to latest 5.x and i have lost my
subwoofer sound. only left & right satellites are making some noise
but without bass it sounds not good. now i have gone back to latest
4.x but subwoofer remain lost. are there any screws i can turn?

regards

ProgDVB itself does not know about your subwoofer or how it's addressed by your sound card.

Does this also happen on normal stereo audio?
If so, there's something fishy with your audio drivers and / or settings.

If only happening on AC3 audio, the cause should be the codec with it's settings, or perhaps the renderer. Try to build your own graph.

Or are you talking about SPDIF from an SS1 / premium card? Then it may be related to the plugin used for this.

Another chance, 5.x test versions aren't really reaqdy yet, and since the latest versions of ProgDVB, a few features are available from the Pro versions only.

Some additional functions, such as "Picture in a picture"(only in 5.x), AVC/H.264 and DVB-S2 support, work with several audio streams and some other, are available in ProgDVB Professional only.

I don't have any of that Pro versions to test on and play around with
And no, surely I won't give away some of my really small private budget, to improve my chances to support for Prog, for no return at all...

However...
As usual, details rule, as we're talking technical issues here.

Anyway, I don't have any multi channel audio system here, 'just' a fine vintage stereo tube amplifier from 1966, so someone else would in case have to proceed on this.
