Accessing vendor service in the vendor Audio effect module failure!

[Varun B]

I'm trying to access a vendor service, in custom audio effect module. Vendor service is visible in " vndservice list".

All registered effects are loaded using Passthrough implementation of Audio effect service. The snippet of service implemenatation is as below:

int main() {

    android::ProcessState::initWithDriver("/dev/vndbinder");

    android::hardware::joinRpcThreadpool();

    defaultPassthroughServiceImplementation<IEffectsFactory>();

    return 0;;

}

When i try to enable the particular effect which accesses a vendor service internally, defaultServiceManager()-> getService(VENDOR_SERVICE) is getting timeout.

I found that "android::ProcessState::self()->getDriverName()" is still "/dev/binder" inside the custom audio effect module create() api. 

Please provide your inputs on how to achieve this.
