I have run HD-installed Knoppix 4.(6 i think) with Kernel 2.6.11 dual-booted with windows XP for quite a while now, and have had no real problems with it at all. However, recently i have booted up Linux (because windows got screwed, but that's not for here :haha, to find that my sound no longer works... the KDE Sound System complained that it could not play sound when i started up, and i thought, OK... thats wierd, and i tried to play a music file in XMMS and that also said it could not find the soundcard / make sure its not in use. Randomly messing around, in silence i tried running some demo programs that i have on my windows partition with WINE to see if it will work, and i came to Brullwurfel.exe [this is a program that contains a player, and plays files contained within itself sortof like Tracker or something, It played sound... i couldn't believe it but sound was coming out of my speakers... Also, sound works when running the games that come with this version of Knoppix (frozen bubble, Enigma etc...) I can also play things using XINE (however, this is a movie player, but it does play my MP3s, and it works) and i can also play things using modplug player (windows program opened with wine) im wondering if there's something thats reset to default or something, and XMMS and KSS isn't finding the sound card anymore, and also where my soundcard device might be located, or how i can find where it is. XMMS seems to suggest that "default" is /dev/dsp but, that's not working, XMMS, KSS and Audacity, none of those find a sound card, but other things, that dont really require sound setup... do... So, how come these programs can play sound, but KDE Sound System and XXMS can't? Also, how to find out where my sound card is at, would also be good . Any ideas? :bounce: It is also strange that the sound suddenly descided to not work... myself having done nothing to it whatsoever for quite some time since it last worked.
