[linux-audio-user] Cheap 5.1 soundcard?

Hi, as the onboard soundchip on my Epox 8RDA3+ (CMedia 9739) doesn't work very well, I'm looking for a cheap soundcard which can handle 5.1 sound. It should run under Linux (Debian Sarge, Kernel 2.6) and Win98, and I want to be able to play AC3 sound (that can be done in software, right?). I've already looked around and found several cheap 5.1 cards, but I have doubts about their Linux compatibility... Can you tell me something about these cards: Creative Soundblaster 4.1 Digital Creative Soundblaster live 5.1 Digital Typhoon Acoustic Six 5+1 Terratec Aureon 5.1 Fun Is any of these cards well supported by Alsa, and can I play 5.1 and AC3 sound with it? I've already nearly decided for the SB live 5.1 Digital but then noticed that it's not that well supported... Or is there any other card which you could recommend? I don't want to spend too much, it should definitely stay below 50 EUR, but I don't have high expectations (playing MP3s and games, watching movies, getting system sounds...). Thanks in advance for your help, Oliver Gerlich
