I think I have a very similar problem to yours except that I have TV audio on the left hand side. I'm still testing my problem and trying to find a solution. My findings so far: - if I unmute line in, audio is perfect with tvtime - if I mute line in, I get sound from the left speaker in myth. However, sound from the right speaker is not simply static, it is recording form the mic! Yes, that's what is happening: left input is line-in, right input is from the mic at the same time! Please check if this is your case, too. I have two mic plugs, one in the front, one on the rear side of the machine, so if you happen to have a similar PC, you might need to also select the correct mic in kmix to check this. - I can reproduce the "pop" sound getting louder, can't remember which setting influences this in kmix, but by playing around with controls I could easily get rid of this problem. I cannot check this right now, as a longer recording is in progress on my box. - the problem does not seem to be related to myth however: if I eg. record sound from line in with krecord, the same thing happens: the left side is recording from the line input, the right side from the mic. I suspect the problem is that the sound driver is incompatible with the mixer circuit in the integrated sound card. My motherboard is an ASUS A7N8X-X (nforce2 chipset). Recording works perfectly under Windows, at least. I have no idea where to go next, already tried google, without success. But I'm not an expert in Linux...
