[PATCH] Azalia bug in codec Realtek ALC892

[Jose Maldonado]

Hi, everyone!

Right now I'm using OBSD 7.2 (my first time in OBSD) and the only issue 
is my onboard audio. The audio randomly stuck (listen music or not, with 
high CPU use or not) and only a hard reboot give me back audio to next 
stuck.

In dmesg don´t show nothing, but sndiod -dddd give me this output:

* snd/0 watchdog timeout *

The error appear in debug info and my audio is gone. The issue is not 
new more info in this links:

With this info I realized this patch (directly on OBSD-stable source, 
sorry) and...work! Not audio problems in my PC using this patch (one day 
testing, multiple apps using audio, not stuck/not latency problems).

If anybody can test, verify and give OK to this simple patch, I would 
appreciate it (and I'm sure others would too, specially living in 
-release versions).
