Multimedia Audio Device drivers for 64 bit Windows guests on VirtualBox

If you have installed VirtualBox on your computer and have found that you are getting no audio it is because the audio driver for a 64 bit Windows guest operating system included with the VirtualBox package does not work. You will have to locate and install a driver from the RealTek website. This was the case in March 2010, Sun or whoever are administering VitualBox may have fixed this problem.

This post was made in response to some of the research that I performed in trying to fix the problem for myself. It highlights the nonsense that you often find on forums. Now, May 2012, The forum in question was the VirtualBox help forum.

My take here was a comment about the forum moderator making false statements and then having a go at the OP (or possibly a respondent) about not following forum guidelines.


Windows Update DOES NOT provide a solution and it is NOT a case of following forum posting guidelines.

If you search for "virtualbox multimedia audio controller driver" - it takes you to the VirtualBox forum - Sasquatch - Forum Moderator has the arrogance to "bark" at posters for not following forum guidlines!

The solution was found on RealTek website - AC'97 drivers - worked on both Windows 7 64 bit and Vista 64 bit guests hosted from Windows 7 and Vista 64 bit hosts (both with processors that had hardware virtualization capability)

"muse sound driver windows 7 64 bit"

I am not sure what this means.  I am not the author of any such drivers

Win 7 32 bit Guest on 64 Bit Host

Here is Windows 7 Home Premium 32 bit running on a Windows 7 Professional 64 bit host:

If you look at the bottom right below the Guest's information window you will see that DVD43 is loaded and ready to copy.

Award BIOS

The Award BIOS - With M.I.T - Intelligent Tweaking

Unlike some of the BIOSs that are used in "brand name" desktops and in most laptops, the Award BIOS seems to be feature packed. The details of the BIOS options and the screens can be found  in the motherboards owners manual, so there is no point in repeating them here.

Tools to unlock Insyde H2O BIOS

Tools to diss-assemble executables and dlls

There are many tools available for you to be able to inspect your computers configuration files. These can be dedicated programs that specifically are designed for that purpose or they can be more general, such as a program editor, that can handle a wide range of binary file formats.

In a discussion with a visitor to this site the tools mentioned above were cited as being useful when looking at ways of unlocking the hidden menus in Insyde H2O BIOS/CMOS. The issue here is the confusion over what and where a "pre-boot" environment resides on a computer. The pre-boot is  lower-level  w.r.t. code and is operating system agnostic. Using a Windows dis-assembly tool can only be of limited use here. 


NikiDebuger is a basic Windows debugger engine core which can debug the application running under windows 32 bits platform. NikDebugger provides the basic debugging features to the windows developer to find bugs and troubleshoot their applications. Its a simple but effective application which has small executable size (130Kb when zipped i.e. easily downloadable). Shows assembly code view (intel x86 32-bits family processors disassembly), register view and stack view apart from application debug output.

The Dis-Assembly viewer application is build over the NikPEViewer



An ITX format PC - Small Desktop Media PC - SDMPC

At the present time there are a few Atom based ITX motherboards and now AM2+ (AM3) and 775 socket boards are coming onto the market.

An investigatory exercise was made to see the viability of a Quad Processor based SDMPC

The requirements here are for a small media computer that has one HDD (possibly a 2.5" SSD) - just for booting, an intregal video chipset and enough USB and/or external SATA connections for external drives.

There is no requirement for an optical drive (BD) as all the media is to be stored on external SATA drives in docking station.

Zotac ITX Motherboards

There seem to be 3 different Intel boards and 1 AMD. The preference was for AMD
Saw a mention of a DFI (a company) unleashing an Intel lga 1156 socket p55 chipset based mini itx board in Q1 2010  - decided to go with the Zotac

Zotac GF8200-C-E Motherboard

This was ordered with an AMD Phenom II X4 CPU. The CPU, at 140W, will have to be used on the Windows 7 box as the ITX board has a recommended 65W maximum TDP for its processor. It is not known at the present time whether the AMD 550 (95W) will be safe to use on the ITX I may have to re-source for a lower TDP chip.

Trend Micro - WTP

I first came across Trend Micro due to observations of visits to my website. The server logs were shown WTP add-on in the browser identification string.

RTMP - Real-Time Message Protocol

I am approaching this in a rather backwards manner. Having been interested in this from the perspective of wanting to be able to download from BBC iplayer, having managed to access the service in Canada (first using Tor and now via a VPN), I am now in the process of working out the inner workings of RTMP.

This page represents an on-going research project into the downloading of media streams from the Internet. This started off with the analysis of get_iplayer and the techniques used to download BBC programming. It is being extended with a goal of having the capability to capture other UK TV such as Channel 4 (4OD) and other international feeds.

Many pages relating to this project were located on my website - these are currently being migrated to this blog.
