I have build a small player to play MP3’s.
When I run it without any intenset background activities everything runs very well, but when I for example open a DOS bos and start some CPU taking activity (UPX for example) the sound “hacks”.
I have set HWND, I use DirectSound together with FSOUND_INIT_GLOBALFOCUS or FSOUND_INIT_ENABLEOUTPUTFX and I have a buffer of 200ms.
Any hints how I can avoid these “hacks” ?
Thanks in advance

Thanks for the answers both of you.
I had set the buffer with FSOUND_SetBufferSize to 100, but have now made this setting user controlled, so if anyone needs more they can set it.
Cannot afford loosing the spectrum, so I will keep running it via a SW mixer.
Look also that if you have Win9x kernel, you’ll get this kind of problems when using waveout and smaller buffer sizes (<250 ms). You may try using DSound.
With NT kernels, you should be able to set buffer around 100 ms and hear no hacks in most situation, even intensive use of CPU and even with waveout driver.
