KNOWN ISSUES:
- PCM slider in Alsamixer/Retrovol no longer works

I am finding that alsamixer won't start at all. It gives the following error:
Code:
# alsamixer
invalid card index: "


It appears to be having trouble with the "card" definition in this stanza:


Code:
pcm.looprec {
    type hw
    card "Loopback"
    device 1
    subdevice 0
}


Retrovol runs fine though.

Do you think it might be possible to make any change that keeps alsamixer happy and lets it run (despite the loss of PCM slider as you have indicated) or is this just an unavoidable side effect?

EDIT : Strangely - if I enter "alsamixer version" into a terminal then alsamixer does run! (Wrong syntax to tell me which version but hey, it opens the alsamixer gui!)
It seems to look slightly different (fonts harder to read) but at least it runs. Weird.
cheers!

EDIT 2 : Alsamixer is version 1.0.26 and this is on a Slacko 5.6 derivative.

Hey Greengeek

Sorry, but I have no slightest idea what and how should be changed, I don't get this syntax at all...
Just tried it in Fatdog and Alsamixer/Retrovol work well (except PCM), but YT in Chrome is mute.

Greetings!
