Channel Mute on direct sound patching ?

[Big C]

I'm currently using a Delta 1010LT card and patching sound directly from the In 3/4 channels through to the Out 7/8 channels. I want to keep this configuration in place but also have the ability to mute individual output channels i.e. only channel 7 or only channel 8.

Is there anyway of doing this using the the functions available within DELTAPNL.DLL ?

Driver version : 5.10.00.0048A

Yes, at the bottom of each channel in the control panel there is a Mute button.

Hi Paul,

I installed the latest driver (Delta_V32_5.10.00.5069v3.exe) onto the PC and the 'mute' options are now available. What I now need to do is be able to control the mute buttons through my software, do you know where I can download a SDK that is compatible with the above driver version.

Thanks.

What software are you trying to use? How exactly do you want to control those mute buttons?

What software are you trying to use? How exactly do you want to control those mute buttons?Hi Paul,

I'm working on a Voice Comms Application that runs in Delphi. Depending on a couple of things, the app will provide voice to a user in both ears, only the left ear or only the right ear. So what I need is an API call that provides the same function as clicking on the mute buttons on the DeltaPnl interface.

I've had a look at the functions available within 'DeltaIIpnl.dll' and there appears to be a couple that may be appropriate but I cant find an SDK that includes these within a C header file.

ps. If there is something similar within the current SDK for the Delta 1010, Driver version : 5.10.00.0048A then that would also be very useful.

I've switched over to a second system which has driver version : 5.10.00.0048A installed.

Using the SDK for this driver I can call the 'dpSetDevVariLevelOut' function and use it to set individual output levels.When I set the level for an output channel to it's lowest value (-15?) I would expect the channel to be muted, however I still hear voice.

Is it possible to mute the outputs using these levels, if so what value should the level be set to ?

bump - Can anyone help with this ?

[Big C]

Would really appreciate it if someone could help me with this one. I need to know the header details (input parameters & return value) for the following functions available within DeltaIIpnl.dll, Driver Version Delta_V32_5.10.00.5069v3.exe :

I sent an e-mail to see if I can get any info on this for you.

Thanks very much :thumbsup:

Unfortunately I never heard back. I asked someone else and was told that we are unable to provide any support or assistance with the SDK.

thanks for trying to help JA. Appologies for keeping on about this but my company has bought 30+ of these cards and at the moment it appears that it may not be able to do what we require !

I'd like to repeat a question that I've already asked but has yet to be answered:

Basically, using driver 5.10.00.0048A is it possible to mute a single channel using the 'dpSetDevVariLevelOut' SDK function. I've tried using it but I cannot find a level* that actually mutes the channel.

*value passed into the 'dpSetDevVariLevelOut' SDK function.

I have the same problem...

I have a similar question I would like to mute the individual input and output channels on my Delta 66 from my own software. Is there an SDK for this? An API by which I can control the cards in a similar way as I do with your control panel application? Please help! I am developing a control system for a video conference room.
