I just purchased a Logitech G930 Headset that has stereo surround and a microphone. Slackware version 13.0 with KDE4 works with the volume control on the headset but Slackware current does not. Neither version works with the three function buttons on the headset.

I am able to listen to the stereo headset (without surround) and use the microphone.

I'm very unclear about what support is in Linux or KDE4 that might allow me to use the function buttons and I would like to get at least the volume control working with current. I can adjust the volume using the KDE mixer, but not the volume wheel on the headset.

Any suggestions about where to find information or how to support the remote control functions will be greatly appreciated.

first delete the /etc/asound.state file then reboot. this forces slackware to read your devise and write a new one. then open a terminal and type alsamixer.
then press F5 turn up volumes and enable head phones set input to mic set capture and turn up the mic boost have fun.

the gui way. I guess click icon then settings then configure channels you want to use enable them and select input mic capture turn them up, turn up boost mic.

the other alsa oss mixer. Kmenu -> applications -> multimedia -> mixer select controls . enable select mic input select mic mic boost turn it up. if you have a head phone enable do it.
all three of those programs are linked to alsa. all three will do the same thing set one you set them all.
when upgrading from 13.0 to current you must read upgrade text
because there are packages that have to be removed.
the CHANGES_AND_HINTS.TXT is a good idea to read.
If it was a fresh install still read them.

KDE 4.5.4 from Slackware current seems to have fixed my problems with the volume control wheel on the headset. It is working again to remotely control the volume.

I have not investigated support for the other function buttons so I'm not sure if that is possible.

Thanks to all the Slackware team and supporters for the hard work making current better and better.
