Hi all, I believe I'm correct in saying Pulse doesn't support DD/DTS passthrough (yet) so what I want my system to pass the decoded output to my amps analogue inputs. I don't think this is a problem but I want it setup in a way that mimicks my amps decoder and I'd like to know if it's possible. My amp is configured with 4 speakers (no centre) and each is set to what the amp calls 'small' i.e all bass output below the crossover frequency is passed to the sub ASWELL as the discrete LFE channel. Centre information is mixed into FL & FR speakers. Now I know a 4.1 setup is possible in Pulse with a config line like; load-module module-alsa-sink device_id=0 channels=5 channel_map=front-left,front-right,rear-left,rear-right,lfe The problem is, I'm assuming this is passing full range signals to the main speakers and only the discrete LFE track to the sub, this also suggest to me that playing audio tracks that don't have a discrete LFE track (2ch music for example) would not output anything to the subwoofer? Any advice welcome, thanks Dom
