Potentially, though I suspect it was just distorted because the volume 
controls were set too high rather than being permanently damaged.

There are a couple of GUI mixers for FSO-based distros. Both are mentioned in 
the wiki now. fso-simplemixer may need a small edit to work with recent fso 
versions though.

The software change is a proper fix, not a workaround, and the capacitor is 
unnecessary even with rootfs on SD. If you read that thread in full you will 
see that the fix was to properly use the chipset's SD drive strength control 
rather than just set it to maximum.
