The active speakers don't have vol controls, just trim pots for various freq corrections and RCA and XLR inputs, so it's just PCP (squeezelite/jivelite?) that is doing vol control. Hmm - maybe wrong thread! The ALSA mixer settings were at the those you mentioned already.
The noises are: 1) Boot up squealing 2) Background hiss 3) Transport change (vol/pause etc.) clicks After some testing I found that if I switched to a USB DAC with the display back on, the boot up noise disappeared so it's something to do with the DAC HAT. I found that the noises are in time with the activity LED so I guess there's some interference issue. Background hiss varied widely between different DACs. The transport/vol change clicks/glitches are definitely more noticeable using RCA (12dB more sensitive than XLR) and on quiet tracks. I can hear them now with the same tracks on other Squeezelite systems connected to active monitors, so is it just an artefact of Squeezelite playback? I just don't hear it using Foobar2k direct to a DAC. Changing the ALSA buffer from 80 to 240 has helped a little I think with one SPDIF DAC system so far. Will do some more testing. Maybe these monitors are just too revealing! :-) ------------------------------------------------------------------------ mr-b's Profile: http://forums.slimdevices.com/member.php?userid=10044 View this thread: http://forums.slimdevices.com/showthread.php?t=103330 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
