[mythtv] PATCH: full duplex on Asus A7Nxx boards

[Chris Derossi]

I have an Asus A7N8X that uses the nForce audio. I'm running RH8.0 with
OSS sound; I did not install ALSA.

The driver reports, apparently incorrectly, that /dev/dsp does not
support full duplex. However, there is a problem with the driver
improperly making the /dev/dsp device unavailable for writing, which
breaks sound output.

The following one-line patch avoids this driver problem. With this
change to 0.8, everything worked great.

[Note: I don't have enough context with OSS to understand whether this
is a driver bug, an OSS API bug, an intentional choice, or a design
flaw, so I'm reluctant to change the driver. But I do know that this
change to MythTV avoids the problem.]
