Please disregard this report. Issue solved as it was caused by a fault alsa install. Sorry for the inconvinience.

[Andrew B (andrew-berridge)]

This is an error in the coding of the gmixer script. Under certain conditions (indeed, due to invalid/faulty alsa install), the program flow gets to line 1013 and calls sep.hide() where sep is not defined. The variable sep is defined twice in a prior if then else structure. However, there's a possibility of neither the if or else condition being satisfied.

Please could sep.hide() be moved into both of the conditions?

Same bug in Ubuntu Karmic. Gmixer fails to launch

[tydell (marcin-tydelski)]

in Arch linux too.

Same bug with Fedora too :-(

I have this problem too if I select the device "HD-Audio Generic (Alsa mixer)". In alsamixer, this device shows only one, mutable item "S/PDIF" without volume controls. The attached patch fixes it for me.
