Glad you're safe, man. Unfortunately, there will always be some reckless people out there on the roads, among the vast majority of decent and careful people. Take care.

You should demo some of this awesome work on a YouTube channel, kjliew. Earn some well-deserved monetization from your hard work. 🙂

Alright, @dionb, @bregolin and everyone else willing to help me test my progress with this, I just improved the player to display some more detailed PCI info about the detected sound device, including the subsystem ID and subsystem device ID. Could you please try it again with the version I'm …

This is awesome! Just tested it on a 82801CA/CAM ICH3 and all audio files played perfectly. Keep it up! So looking forward to what this brings for DOS gaming on modern-ish computers :) Excellent! Thank you for testing. ☺️ ICH3 is a revision that wasn't originally supported in the source code. I …

First of all: great work! The VirtualBox GPU guest driver for Windows also relies on WineD3D for 3D acceleration in Windows guests. It would be very useful if QEMU were enhanced to support that same guest driver. It might prevent you from having to reinvent the wheel w.r.t. full screen vs windowed …

Because it's not trivial to implement. We're talking low-level hardware interraction through x86 assembler here. I'm not the correct dude for implementing new big things like that. Perhaps this could help: I've dusted off the source code of a simple WAV player for AC'97 sound devices as found in …

Thanks! 🙂 Any help with this will be helpful, both with testing and development. It's actually been a great opportunity for me to further explore my obsession with low-level software development, particularly in assembly and C. I don't have much experience with that, to be honest. It's been a fun …

What's the endgame here? Just a working .wav player, or are you actually contemplating trying to get SB-compatible DOS sound on AC'97 (which would be huge, of course)? My goal is to write an open source VBE/AI driver for this family of audio devices. VBE/AI in an audio-specific extension of the …

I appreciate the effort. I feel kind of guilty asking you to go tbrough those troubles of installing Win98SE again, especially on more uncooperative hardware. Thanks foe the info on the specific codecs! I think my next step is to have the player display the sub-device-ID (or whas it the device-sub- …

So, those Bus correction kits are needed for older revision boards, right? The newer ones like mine has those jumpers and that PROM 'Pqb1' already on board that does the job, if i understood correctly. No, these are different issues. What you are referring to is the ability to disable the onboard …

I might be able to help you with a crucial piece of the puzzle here! 🙂 Years ago, I asked people on the the Vintage Computer Forum whether they could help me obtain the so-called "Bus Correction Kit", an obscure aftermarket product for the Olivetti M24, which someone back in the day developed to fix …

Have any of you played with Dosemu2 yet? It's kind of a resurrection of the old Dosemu project, which was more or less the Linux equivalent of NTVDM, which allowed DOS code to run natively in a v8086 instance. Since v8086 mode isn't available in a 64-bit operating system, Dosemu won't work on such …

This is not true. Such files are not valid WAV files by definition. Of course there can be files that contain only raw pcm data but these are not WAV files. WAV files have to contain WAVEFORMAT or WAVEFORMATEX header and the nSamplesPerSec field is mandatory otherwise no player could play these …

The .TXT file says multiple sample rates supported, but that could explain something. Sounded a lot faster than 2x though... Hmmm, now that you mention it, and after I've taken another look at the code, you're right, it does seem to make at least an attempt to read the sample rate from the WAV file …

By the way, when you tried it with the Compaq TR100 board, did you get the idea that it was actually playing back the file, but just with muted audio? Did it behave like it was playing, so a delay before seeing the DOS prompt that took about as long as it did to play the file on he other two …

Right, can help :) Thank you, fellow Amsterdammer! :) Downloaded player.exe, stuck it on a DOS IDE DOM running 6.22 and stuck that in a few systems. Compaq SW400 motherboard (from AP550 workstation) with i840 chipset and 82801AA (ICH): - unsure about PnP status (no option in Compaq OEM BIOS) - …

So I dusted off an old yet interesting piece of code I found on the internet, that some of you are probably already familiar with: Jeff Leyda's .wav DOS player for ICH AC'97 audio devices. It's small, simply written to do one job, very well documented, with well-structured, well-commented and quite …
