well, mandrake 10 had sound issues right from the start. try this:
enter your password
its pretty straightforward...u select the driver options...and test it each time...
As for your yoper boot problem...what verison is it? i recall 2.0 and below had this issue, but i didnt in 2.1.0. i did however, have issues with XMMS, and using things such as Alsa. so i couldnt IM while listening to MP3's....well i could, i jsut couldnt hear responses
If you can boot into yoper just once, make sure u have a WORKING sources.list (the servers are down now i beleive) and do this:
apt-get dist update
or you can do it in synaptec(?) it will update EVERYTHING. The release i had, had an issue with SMP, and a bootsplash. This updated everything, but as a newbie, id stick with kpackage or synaptec...took my dualy only 40mins to update from 2.0 to 2.1.0, new kernel and all..booted nicely too.
For the newbie, i would suggest giving suse a try. its 1CD, can be installed via FTP server (so no CD's if u like) has (from what ive seen) NO sound issues from the start....has Alsa properly setup...u may have an issue with ur first time on the internet though, as suse hasa little problem with DHCP and eth0 the first time...but its nothing bout 5 minutes tweaking cant fix.
