No problem. I learn too.

Generally a condensor mic needs power, either batteries, phantom or a
power supply of it's own. Ribbon mics are known to be sensitive if the
cable happens to be miswired.

Right, two mics(1,2), two lines(3,4) and two from s/pdif(5,6). The outputs
are similar. Perfect.

Ya meter bridge is kind of funny, the *.desktop file starts it with two
meters that are supposed to be connected to alsa_pcm:playback_1 and 2 so
on my system that means they are not connected to anything. But it is a
handy signal indicator for trouble shooting when not using it for

It is something to remember as it deals only with the sound card where
many other mixers deal with psuedo/soft controls.

Yes M is mute. I have gotten sound out of things using alsamix when
nothing else works. It shows up interdependancies rather well too. (where
moving one control affects another - I have one where muting one channel
mutes three and unmuting only unmutes one)

Probably routing would be a better word than monitoring.

Quite common actually. You control the level with the physical controls on
the box... although it seems with this one the volumes that look like
output may affect the input. The manual was not that clear to me.

Ah, pavucontrol then, controls PA. Fine for desktop stuff like browsing

I think it may be a soft level if alsamixer doesn't show it.

No, just pulse itself.

It is just nice to see someone else enjoy linux audio and not go away
