I have checked and reinstalled drivers, I have also changed the operation mode to AC97 in BIOS and installed drivers for that mode of operation, still no windows sound devices listed but it works from both the Realtek applet and Skype.

The rebuild seems to have worked except i no longer have any sound. Before the rebuild the sound worked perfectly so im sure i have the hardware i need, however when i look in the Control Panel under Sound and Audio devices there is no device listed, the fileds are all greyed out, although the hardware tab does list a Multimedia Audio Controler that it says is not configured correctly. There is also no volume icon in the system tray.

I might be mistaken but from what I can garner online, the Tecra has a Sound Blaster 16 sound system. This means that attempting to install Realtek drivers could result in permanent damage to the chip!

If you had done a clean install of windows there would not be a Realtek folder on the C drive.
Therefore either you have done a windows repair operation or you have already downloaded some software for the sound.
I would suggest that you visit the Toshiba website to get drivers for your model of laptop.

hi, thanks for the link, i downloaded the driver from the toshiba site in your link. It was a sigma tel driver and it gave me the volume icon etc in the system tray, but still no sound (i checked nothing was muted etc and it wasnt). Any further ideas?

I have installed a Windows 7 as virtualbox-guest. My Ubuntu works as host. The sound is stuttering ugly. I tried to change that by changing the Audio-Controller to ICH AC97 and install the driver downloaded from CHIP. Result: After a restart nothing has changed, Sound stutters like before.Is there a way to get a proper sound?The Guest additions are installed and are working fine.

Having experienced the same Windows guest stutter under an Ubuntu host (12.04) - except in Win 8.1 - I found a solution that mostly conforms with Takkat's answer. My stutter occurred with the Windows guest being allocated 4 out of 4 cores, but the execution capped at 75%, with 4GB RAM, and 256 MG graphics RAM. Switching to 2 out of 4 cores - but removing the execution cap - running at 100%, eliminated 90% of the stuttering. But not all of it.

The final 10% - and the total elimination of stuttering - came when I switched from the default PulseAudio driver in VirtualBox Manager's settings, to the ALSA Audio Driver. Please note, prior to the aforementioned reallocation of CPU's and execution caps, I had also tried this driver change, and it did not remotely eliminate the stutter. The two changes in combination was required.

To minimize effects coming from limitations of a virtual machine we therefore have to make sure to assign as much hardware ressources to the guest OS as possible, but make sure the host OS is still able to perform well (including Pulse Audio in your case!).

This happened to meet too, for some reason the CPUs were on 4 of 8. I use a Macbook Pro running OS X 10 and Windows 7 using VBox. When I put the CPUs down to 1 it started working much better. check it out.

Installing virtualbox guest additions didn't help to recover sound. Then I downloaded and installed Realtek AC97 Driver from realtek.com.tw on guest machine and sounds works now with PulseAudio and Alsa Driver as host driver.

I gave it a go, and it it does seem to work... partially. I can get sound working, but not Midi. I'm able to select General Midi address 300 or 330 successfully, but both are silent when I try to test them. Is there a way to get some form of Midi working in games like Duke 3D with this chipset? It's a long shot, but I just thought I'd ask anyway.

So, yes, the simple answer is you can't get MIDI music from DOS games, regardless if they are played on Win98 or pure DOS. The fact the you still get some sound from DOS games, is because the AC97 driver stacks provide an SB emulation layer for wave-out. No every games work on such emulation as not many people really care. If the games uses other part of SB, such as the OPL2/3 sound generator, then you will be sorry.

Sorry about that, I wasn't sure whether to post in the DOS or Windows section, because I'm asking about running DOS games within a Windows 98 environment, and using Windows drivers. That's why I thought posting in the Windows section seemed right.

Old hardware and driver questions should be asked in Marvin. DOS is for DOS games themselves and Windows is for Windows games. If you read the forum descriptions it is pretty clear what goes where. It makes it easier to search when you only have to search the relevant forum rather than having to waded through the entirety of VOGONS. Think of VOGONS as a large valuable database with lots of information. Posting threads in the wrong forum is like misfiling things in a very large file cabinet.

Okay, thanks. I will post my questions in Marvin in future. Annother thing that lured me here was batmreload's thread about SB16 Emulation [url]Any SB Live! users out there using the sb16 emulation?[/url}

Are you doing this from within windows, or the pure DOS prompt?
In case of windows: Windows XP has a build in soundblaster emulation, Midi is also mentioned.
In case of the DOS prompt, what emulation driver did you load?

If this is a Pentium 4 or AMD Athlon mobo, I would be happy if there is a basic DOS soundblaster emulation driver available. Some of them may support some sort of Adlib music emulation. MPU-401 midi emulation was normally left out at that time.
Adlib is the same as 'Sound blaster FM' and OPL2, which is almost the same as 'Sound blaster Pro FM' and OPL3.

Note that there are two ways of emulating MPU-401 midi:
- MPU-401 interface+Wavetable in software, requires a sound patch set, such as the AudioPCI and SB-Live! .ECW files.
- Emulate just the MPU-401 interface, and route the midi data to the joystick connector, for attaching an external Midi module. Vortex-2 and YMF-724 cards do this in DOS.

You may be onto something there. I should probably have mentioned this earlier, but when I install the drivers, it loads a driver for MPU-401. You are also able to set the address in my case it's 330 and IRQ which is 5.

Is there something else I'm supposed to do to get it to work, like load a soundfont? In the list of Midi devices in Windows 98, I have the option for Microsoft GS Wavetable, and then Roland MPU-401. If I select Roland MPU-401, Midi files go silent.

So it does indeed seem to support the MPU-401 interface. The question is where that MPU interface routes the midi data to:
-Does it go to the joystick connector, and thats that? An External module, like a roland SC-55 for example, is the thing to test that.
-Or does the driver route the midi data to its software synthesizer, or any other software synthesizer for that matter, which would not require any additional hardware.

Note that the original "Sound Blaster 16" did not include a wavetable midi synthesizer by default. It came with a FM/OPL3 music chipset onboard. Does that work?
It is kinda interesting that it supports "Sound Blaster 16", since only Sound Blaster Pro 8-bit compatibility was ever legally licenced out.

The mpu-401 routes midi data to the gameport or wavetable header of a soundcard almost always. If the card does indeed have a software synthesizer available in Windows, it should be listed in Windows 98 Multimedia Properties (in the control panel). If you don't have an external module or wavetable header module, then it makes sense you get no music using mpu-401.

It seems like it routes MPU-401 through the Game Port, because if I select it as my default midi output, I don't get any sound from Midi files in Media Player or Dos games. I can't seem to get the software synthesizer working (assuming there actually is one.) There's no FM synthesis whatsoever either, emulated or otherwise. So wavetable synthesis is my only hope here. I just don't know where to look or what to look for to try and get it to work.
