		+	Using an LSLive v2 + Freelink I was able to produce sound but with the following (major) caveats.
		+
		+	* Using Alsa is not possible without changing the kernel. Alsa does not play well with the EABI / OABI change and does not seem to work even when the kernel supports both ABIs. This is a problem with the userspace tools and not the kernel. This will presumably be resolved when running an armel system like lenny.
		+	* Using OSS I could get sound playback (including mp3 decoding using mpd) but when the buffer was empty (press stop / file end / etc) it would hang the process and only a reboot would regain control. This was using a cheap "3D Sound" usb device with a JMTek chipset (ID 0c76:1605).

	If you happened to be an LS II user, when you try to play you might encounter FP operation issue (explained in section 1). If you hear cluttered sound output, see 99% CPU usage, use ‘time’ command to start your program and see most time are in system, you probably have FP performance issue here.

-	The solution is to find an integer decoder or player (mpd worked fine for me (Bauldrick) with ncmpc). There should be a seperate artical to list all the integer decoders and players. Maybe even a download section.
