I think this time, the bridge does its job as expected: the track it receives from LMS is 48000 because you have told LMS that the Marantz only supports up to 48000. You have also set pcm mode to wav only. So when you set sampling rate to exactly 96000, it will upsample to 96000 and send that in a wav format to the Marantz When you set sampligin rate to no higher than 96000, the every track below 96000 will remain untouched and because 48000 is received, its a match I agree that we dont need multiple resampling, hence the logic was to choose where you want it to happen: in LMS or in the bridge I added these full processing, options for 2 reasons - features: true gapless, replay gain, fading - compatibility: by sending the same format always to the UPnP player, one can expect better compatibility Now you can decide to have, for example, C3PO do format and rate adaptation and it certainly has more flexibility, but unless you send pcm to the bridge, you wont have the features and if you do youll use maximum network bandwidth which a resource that Im trying to preserve So, and again for the sake of tests, the max sample rate that is wha the bridge reports to LMS should not be set to a value lower that the resampling rate. Its not making it work incorrectly, but as you said, it multiplies resampling for no reasons. As soon as you play with resampling and full processing mode, you could let the max sample rate to 192000 or higher LMS 7.7, 7.8 and 7.9 - 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB2.
