 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Nothing new or original about my ideas, but I would tray to 1) run as Administrator, 2)tray compatibility modes 3) change video drivers 4) if system has integrated and discrete video card I would try both of them (run with graphics processor..." Not so many chances , but I would check/ask question this for searching reason of problem https://github.com/OneLoneCoder/olcPixelGameEngine/issues |

Almost certainly that you haven't got the required audio DLLs. Check the various threads for how to start without audio. |

Thanks for your tips! "run as Administrator" and "tray compatibility modes" I already tried, but didn't help  I didn't want to change the video driver because I think Windows 10 automatically installed the optimal one - and the laptop only has the integrated "Intel graphics unit" so there aren't many options.Unfortunately, nothing enlightening could be found in the olcPixelGameEngine issues. That was a really good tip! It's quite possible that I didn't install anything "special"! Now I just have to find out how to start MMB4W without "audio" or maybe even which DLLs are missing and install them... Thx, bfwolf! |

To give you an update: Success! I found no hint, how to disable audio, in the forum topics.. But I had a look into the MMB4W sources - in main.cpp I found some parts that let me assume that giving '0' as 1st arg should do it - and this worked!  BTW: Does a reasonably up-to-date manual for MMB4W exist somewhere? (PDF? Link?) bfwolf |

It was explained im MMB4W manual  But looking into sources sometimes really helps  . From a command line prompt in Windows , you can start MMBasic running a BASIC program in a number of ways as follows:- One can also create win shortcut and edit cmd properties.

Many thansk for all your help! Thx!!! That helped! A few minutes ago I searched the Windows directory for "winmm.dll" - I "felt" that I had about 20 "winmm.dll" instances in various subdirectories - with different dates. There is also a "winmm.dll" in C:\Windows\System32 and I tried to copy a slightly larger one with a slightly newer date - but Windows "doesn't like it" (i.e. refuses). Yes - after I downloaded the PDF of the "most recent" MMB4W manual, I found the relevant section. So until I have solved the "actual problem" with the "winmm.dll", I can live with the first argument '0' for mmb4w.exe - then I just have no audio.. Who cares?  In olcPGEX_Sound.h in the MMB4W source there is the instruction #pragma comment(lib, "winmm.lib") and that already points to the "winmm.dll".. Or is in fact another DLL to blame? bfwolf |
