Generally, no sound, except:
1) "aplay" works OK with test (.wav) files, but only if I use "-D hw:1,0". Using "-D pcm.cards.default" indicates the file is "playing", but no sound.
2) Used to get "event" sounds OK (opening, closing windows etc), but this has vanished. Don't believe anything was accidentally changed.
3) No sound when using the screen menus, even though my 2 cards are detected. Card "0" is a Soundblaster in a PCI slot, card "1" is the motherboard chipset (VT82xx).
Have tried for weeks to understand/fix these problems, but no luck.
Any suggestions appreciated.
