Ok, so my computer had several viruses, one of which somehow removed Soundmax, and my audio driver. So I reformatted my computer to get rid of the viruses , and it went pretty smoothly, all except that I require the HDA Audio Bus Driver in order to reinstall Soundmax. I was wondering if anyone can post a link to where I can begin this download, provided it is not a program that repairs all drivers, as I have found those to be inconclusive. I appreciate the help.
HD Audio Bus Driver
The HD Audio bus driver is the only software component that directly accesses the hardware registers of the HD Audio bus interface controller. The bus driver exposes the HD Audio DDI that its children--instances of the function drivers that control the audio and modem codecs--can use to program the HD Audio controller hardware. Handles interrupt service routines ISRs for unsolicited responses and propagates the unsolicited responses to its children. For each codec, the bus driver loads one function driver if available for each function group that it finds within the codec. Our new feedback system is built on GitHub Issues. Read about this change in our blog post. The HD Audio bus driver: Queries the codecs on the bus and creates children to manage the codecs. Passes commands from its children to the codecs and retrieves responses from the codecs. Sets up the DMA engines that transfer data to or from the cyclic buffers.
