I have added basic sound volume control to Flit for ALSA-configured TinyCore installations (in addition to the prior OSS support) in this new version 1.1.0.
For controlling ALSA, Flit uses the amixer utility that comes with the standard alsa.tcz TinyCore extension. If you can compile your own applications and would like to give this new ALSA support a try, please do so and let me know how it is working for you. If you cannot get Flit to work with your current setup, please PM or post the output of amixer for me to review and maybe tell us the the specific sound hardware you have.
I also adjusted the color definition for Flit's 'transparent' style to work better with dark-ish backgrounds, including the new default background for TC Linux.
If this new version works well for most people using either OSS or ALSA, we can update the official Flit extension the TC repository. Source code and help file attached below.
