[AG-TECH] Dropping OSS device in Rat (Linux)

G'day all

This is just a quick email to see if anyone else has been experiencing
an issue that I have been having lately.

Basically on my "Linux" systems (Fedora Core 6 and Fedora 7), sometimes
when Rat is started, the Device "OSS" device is missing in which is then
defaulted to an "ALSA" device.

The reason why this is an issue is the "OSS" device produces far
superior audio quality, when compared to "ALSA" (Though I realize that
"OSS" is just a wrapper on ASLA with the default Fedora Kernel).

>From my understanding, the reason why this occurs is that, if the OSS
device is in use, it then becomes unavailable and no longer displayed as
a device, as OSS only allows one application exclusive access.

Anyway, from doing some basic testing, it was seen that events like
switching from one venue to another was causing this to happen.  It
appeared that if the machine was heavily loaded, this would increase the
chance of this happening.

Anyway, to cut a long story short, I deleted the /usr/bin/rat sym link
and replaced it with a basic shell script:

	#! /bin/sh

	sleep 5
	exec /usr/bin/rat-4.4.00 "$@"

>From some initial testing, it appears to have fixed the issue!  (More
testing is required)

I'm just wondering if anyone else has experienced this issue with Fedora
or other Linux systems???

Thanks for your time,
Jason.
