When switching the analog output source from, for example Speakers to Headphones, a loud "POP" noise comes out of in the Headphones. I'm not too familiar with the oxygen code, so I'm not sure if this was a proper way to do it: I added a call to "xonar_disable_output()" and a short sleep (I used anti_pop_delay) right before when the analog output source is changed (at line 837: sound/pci/oxygen/xonar_pcm179x.c), then a call to "xonar_enable_output()". This has reduced the loudness of the "POP", although it still exists. I'm wondering if anyone has a better solution than this? I tried a suggestion of muting the output and sleeping in this bug report: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1380046 amixer -c 0 set Master 1+ toggle sleep 1 amixer -c 0 -q set "Analog Output" "Headphones" That did not change anything. >From what I gathered on the web, this "POP" issue affects more than the STX, probably all the cards with relays for switching the output source. ------------------------------------------------------------------------------ Go from Idea to Many App Stores Faster with Intel(R) XDK Give your users amazing mobile app experiences with Intel(R) XDK.
