Found the problem. The correct driver is snd-sb8 - or at least this one works. See this post on the Ubuntu forum: http://ubuntuforums.org/showthread.php?t=284405. I used the same /etc/modprobe.conf, i.e., blacklist snd-opl3sa2 blacklist snd-nm256 alias snd-card-0 snd-sb8 options snd-card-0 index=0 options snd-sb8 irq=5 port=0x220 dma8=1 install snd-sb8 /sbin/modprobe snd_seq; /sbin/modprobe snd_opl3_synth; /sbin/modprobe --ignore-install snd-sb8 && /usr/sbin/alsactl restore >/dev/null 2>&1 || : remove snd-sb8 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-sb8 and it works like a charm! Funny, I Googled for weeks and never came across that ubuntu post till I tried "inspiron 3500 opl3sa2". Just goes to show that all answers really ARE out there, you just have to ask the right question. Thanks to all who helped out.
