Hi everybody Here's a problem which I can't solve by googling, but maybe you can help? I have a USB sound card - Focusrite Scarlett 2i2 (lsusb dump: http://paste.yt/p2674.html) It's running with the snd-usb-audio module (lsmod dump: http://paste.yt/p2675.html) I'm running on Kubuntu 13.04, but this has been a problem for a while. The issue is this: """ Every time the sound card is initialized, it goes through a series of loud and annoying pops and clicks. They seem fairly regular, and always follow roughly the same rhythm: click-pop-pop-pop-pop, occasionally with more pops at the end of that. It seems that this happens because/when the external DAC is powered up. As long as I play something (like background music), this problem goes away. """ I've observed that it seems that pulseaudio releases the audio device when it hasn't been used for a while, thus leading to it being re-opened later. I'm experimenting with running "mplayer silence.wav -loop 0" in a screen, and this seems to solve the problem, by keeping the audio device open all the time. Is there any way to have pulseaudio keep the device open at all times? Or some other way to debug this? -- Med venlig hilsen Christian Iversen
