Re: new Studio user writes
Do you need both sound devices? If you only should need the EMU card, you could disable the on-board sound device, by the BIOS settings. Theoretically you could use both cards, there's a special bridge available, but I guess it wouldn't make sense. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

OK. Yes this sounds a good idea.

OK. Will check the xruns displays or use the 'Messages' button next time.
No, Audio has been good, no glitches. The low latency kernel is great.
AMD at 1.9 or 2 GHZ, I know I can expect them sooner or later.

Wow. Thank you gentlemen, Ralf, Abe, Adam, Kaj. Just great. The SB Live card is OK. I can distinguish between it and the onboard Via chipset. And load Soundfonts into it.

Although; Session/Connect/PatchBay, I not sure how I'd save a working complex patch. It seems I am under way, folks. And know I can get back with specific questions if need be. Thank you again.
