<html> <head> <style></style></head> <body class='hmmessage'><div dir='ltr'>I have ati r9 290 I have been using external amplifier that puts the sound into speakers. I have this connection using r9 290 --> hdmi --> speakers<br>And dvi --> pc screen.<br><br>xrandr (that broke my config again) see this external amplifer as a display which is it not. Kde/mint/upstream should fix this so it would be more correct. <br><br>Hdmi channel is just sending audio data to amplifier. And it feels like that ati is using more clock cycles to provide the picture and the audio than it should. <br><br>Is there anyway to prevent this in future? <br> </div></body> </html>
