2014-10-13 03:40:17 Michael Lawton description When switching the port to either headphone ports from the speaker port there is a loud pop in the headphones. When I am playing music through the speakers at 100% volume and then switch, I can hear the music at a very loud volume through the headphones for a fraction of a second before dropping to the proper headphones volume which is much lower. Even if I mute the output before switching ports there is still a pop although not nearly as loud. I believe this is a driver issue (oxygen/virtuoso). The Essense STX uses a relay to switch between the speaker and headphones ports. I am guessing the the power for the speaker (line out) port is much higher than that used for the headphones port and the drivers need to mute the sound at a hardware level before switching to elmininate the pop. On Windows when switching to and from speaker and headphones port the output would be muted for almost a second as the port was switched so there was no pop. On Ubuntu there is no delay when switching ports. I have looked at the driver source code and there is an anti_pop_delay of 800 milliseconds used on the Xonar init method. I think this same delay should probably be added when switching to the headphone ports.
