The most possible reason is that the interrupt is not enabled. I'll check what I can do. Hello, I'm also interested in the SBLive/Audigy working with SBEMU - and I also have such harware available to test. However, is there any good documentation available, a programming model for the SBLive. It …

Update: 1. added option /k to set sample rate. /k22050 or /k44100, default 22050 Thank you for adding /K option. This (28-Feb) version seems most stable by far on Intel High Def. audio. I noticed sample rate of 44.1khz works well, however, you were wise to not make it default, since original SB / …

Except the three I (still) play the most after 30 years: NFS, Screamer, Screamer2, and Screamer Rally. That's OK, I'm super-happy *and* appreciative that you've worked on this project and have such a fantastic success rate so far. I tested NFS, and found it prefers VCPI over DPMI and thus no io …

"You can't use this to make a clone of certain other software" is an additional restriction that the GPL doesn't have, and therefore make DOSBox sources and Mpxplay sources incompatible with one and other. OK, I didn't know DOSBox has such restriction, Does that makes DOSBox source code not …

Hi, I have re-tested the new version and this time it "worked" in the sense that it detected the sound card and I also heard a "pop" from my speakers (I think this is a good sign). But unfortunately testing with Duke Nukem 3D resulted in no music and no sound. The music test did not give any errors …

Yes, I think it'll be good to add Covox support. however for the direct mode, its' complicated. with DMA, I only copy the ISA DMA buffer from DMA controller to PCI DMA buffer accessed by PCI bus master device, that simple enough. for direct mode, even if I'm able to put the sample directly into the …

Any idea if this can work with the MiSTer FPGA platform in the AO486 core? Would be the missing link! The core is otherwise fantastic, but the OPL3 support is lacking and the dev has no interest in finishing it. This project is experimental and as sofakang said, it's not working on his WeCee …
