Phoronix: A Year Later, X-Fi Drivers Still Horrific
After Creative Labs Duped Linux For Vista, it was just a year ago that they had released their X-Fi Linux driver. That initial driver in 2007 had only supported 64-bit Linux, wasn't targeted at newer versions of GCC, and had a whole host of other problems...
Don't buy newer generation Creative sound cards if you're planning on using Linux. Just don't. There are other high-end options that I'm sure are better supported by ALSA. For casual/simple audio needs, the integrated HD audio chipsets on today's motherboards are getting pretty good, and they usually work fairly well with ALSA.
OMG!!! Will that work? If so I could connect my 5.1 on one card and headset into the other!
Yes you can. Multiple sound cards should work just fine. Since the X-FI doesn't have a proper driver on Linux, ALSA will only pick up your Audigy card there, the X-FI will probably be ignored, and should do no harm otherwise. On the Windows-side, you'll see both, but of course, you can choose which one to use ..
So, plug your headset into the Audigy and use that on Linux, and hook your surround-stuff up to the X-Fi and use that on Windows.
