Host/Server: Win7 pro 32 bit | vSpace downgraded to 22.214.171.124 | Flash down graded to 11.2 | Realtek HD audio
- each station has unique local login
- Novell netware client (set to launch after Windows local login)
- Realtek driver version: 126.96.36.19916 Driver date: 2/24/2011
Upon fresh bootup (with no headphones plugged in)
- start video on host machine
Audio comes out of one of the client terminals- not the host.
[IF] headphones are kept plugged in the host machine upon bootup
- audio comes out of proper terminals
Tech support has bug report- case # 00124772.
Sound issues have occured on most all of our deployments this school year.
Many stations effected. (but some work)

This thread reports sound dropping off.
Anyone confirmed the issue may be with Realtek HD drivers ?

The audio settings will show sound coming out of "speakers" (win7 pro 32bit)
The image below shows headphone in host and head set in terminal1)
As long as headphone is plugged in host on bootup, the audio distributes fine.
If no headphone is plugged on bootup, and video is played on host, the audio will come out terminal but not host.
Question: How does nComputing direct sound in a terminal environment? How does it keep the sound separate?
There seems to be a bug with this process.

I was researching why Realtek auto assigns devices and came across the following article to keep Realtek from making changes. So far the changes have had good reults.
I also had to make sure to set the default audio device on the host: (sets front jacks as default)

I have configured almost 10 stations now with the Realtek Settings changes and it has fixed the audio issues.
Here is a screen cast of the settings changes:
Here is the article where I got the idea:
After the making the changes, the audio comes out of the proper terminal. I am waiting to hear from Tech Support as to why this solution works. Hopefully they will post their findings here.
