8 Still looks like loopback is active. Try to find a slider called
9 "Capture" in alsamixer and mute it. There might also be a setting
10 called "input" which can be set to i2c, i2s, mix, etc. Play with these.
11 I had the same problem with a Soundblaster Live 24-bit, and the
12 problem was that it was set "mix", which is a setting that allows you to
13 record whatever is currently playing. It's a good thing to have, but as
14 you can imagine, screws with voice communications, because you're
15 recording not only your own voice, but also the voice of the other
16 person and sending it back right to them.

18 It's also possible to set this in KMix, but I don't know if you're using
19 KDE.
