I've proposed a new logo for ALSA Mixer that is open source app.
ALSA Mixer
Android client for control ALSA volume on remote server using ALSA Mixer WebUI.
(Client-server application for easy configuration of ALSA volume controls using network device (smartphone, tablet, PC, etc.).)
MY IDEA
Proof of the Work
I think, the original logo's idea is ok but it need a bit change and modernism.
I made the lines of voice bar like a circle and it looks like a mixer.
There is a "A" latter and it is the first latter of the app.
Adobe Illustrator CC
