Hello,
This is my first post here, hi :)
I have some strange issue with my setup which I do not understand, maybe some other people here do.
In short I have a self build HTPC for years (i5, 8GB, SSD etc.) and the amps are the Rotel RC-1590 preamp and the RB-1582 MKII poweramp.
I play via Foobar2000 using the supplied ASIO driver for my Rotel (but directsound and WASAPI gives the same issue). The USB connection is Audio Class 2.
Sound is all upsampled via SoX to 24/352,8 KHz (just to prevent sample rate switching, I have 44100 but also higher def music).
When the preamp has to switch on it's input signal this gives a 2 second silence, this is the reason I resample.
This plays fine most of the time, but at some moments, I cannot figure out when it happens after I stop playing a song the amplifier switches back to silence. When I start a song again the internal DAC has to pick-up the signal again so you miss the first seconds of the song.
8 out of 10 times this does not happen. It's audible by a click a few seconds after pressing stop. If it works good, it's good for the entire session.
I tried switching the amp on after the HTPC and vice versa, but I cannot reproduce the problem for some reason in a constant way.
Does anyone have a clue what could be going of and how I can fix this?
If I put a DDC inbetween, like the Gustard U12 I don't have this issue, but I would like to use the direct USB input, because that way I can control the HTPC via de amp's IR remote controller. Also the U12 is just an extra device in the signal path I don't really need.
Thank you very much in advance!
