I tried Musix, a Knoppix-based LiveCD with audio in mind, from Argentina. After a couple false starts due to cables not being connected and controls being set low, things worked well enough for me to get audio out of percheron and then got audio from tape to record, and be saved as an mp3, and be transferred to belgian. That was fairly impressive, but the Spanish language and keyboard layout were annoying to me. When I found my way around that (as simple as entering 'english' at the boot: prompt on startup) things really looked good and I decided to install Musix on percheron.
Big mistake. The install instructions are from 0.30, the current version is 0.59 and things have changed seemingly for the worse. The instructions don't match the installer, and it looks like the most useful install option went away. What I wound up with was an English install with a Spanish keyboard layout (which means '-' and '/' are in the wrong place, thus making fixing anything very annoying indeed) and no network connectivity. The LiveCD could use the network just fine.
As if that wasn't enough, this Debian derived (for Musix comes Knoppix which comes from Debian) thing is almost as rude as Windows when it installs. My Ultima Linux install? Not an option at boot time. Grub merrily gave me several choices for Musix and didn't acknowledge the existence of the Ultima install. After a few spectacularly unsuccessful attempts at fixing that, I gave up and decided that since I had no data to rescue, I could just wipe everything and reinstall.
I gave Musix one more try, and it did the same as before. The LiveCD works fine, but the hard drive install is not fine at all. I blew away that install and now Ultima is installing again, though I do have a partition or two for other things. Other things will not be including Musix.
I do plan to use Musix as the LiveCD does something I find useful. It's just too bad that the hard drive install is so amazingly bad by comparison.
