Re: [K12OSN] esd_ALSA_sound_on_LTSP_4_2 on K12LTSP 5.0.0



Thanks for putting that together Gadi. Your work put an end to my 3 looooooooong days of trying all sorts of stuff to get sound working on Ubuntu 6.06 and Ntavo 6020A's. Hats off to you!

Heh, or you could just *ask* me.  I don't bite.  Hi, Gadi here - I put
together said package.  Actually, to revert back on a K12 box, you could
just ask yum to reinstall the original rpm, and it should put the K12
box back the way it was originally.

I wouldnt recommend just copying back the old rc.sound file, because the
esd binaries in this package are compiled against ALSA (as opposed to
the originals, compiled against OSS), so to revert you would need the
originals.  But, luckily, you are on a package-based system, so yum or
apt or any other package manager you use should be able to reinstall the
original rpm, if you ask nicely. :)

BTW, as long as the version of K12LTSP you are using is using LTSP 4.2,
the package should work without problems.

Cheers,
