The other sound related problem on Peg2/Os4.1

So, for some apps (games/demos) sometimes (not everytime) happenes this:
when apps working music plaing, sounds plaing in random way i have heard some long 'BEEEP' sound. Like blalbalb..BEEEP...blalbalb..BEEEEPP. It's looks like some interupts problem, or kind of .. I use onboard VIA audio. Last time (right now) i detectable it with game GlTron. Menu are works fine (music/sounds/etc), but in game have long BEEEPs. The same for other ones which i can remember right now

Any ideas ? Maybe some interrupt options must be set to some values ? Or maybe VIA driver are bad ? Just tryed right now 'xmoto' - the same 'beeps'.

Rigth now tried 'Giddy' game, the same problems. Also i must to notice, that even if i plug off main speakers, i still have sound on 'on board speaker'. And, the same 'beeps' on it. So, it looks like not driver problem, but somethink like interupt problem maybe ? Maybe some kind of connection beetween video drawers ? Can't believe that noone have any idea of how fix it :)

i have no beep problems here on my peg2, the only issue i have is that the internal speaker can't be muted, it's not even available on the mixer app. I had to unplug the speaker directly in my tower case.

@SoundSquare

So, no sound problems with you ? Your are use default Via or some other sound card ?
Also, you use just default install of os4.1 for peg2, without new updates ? (like maybe new minigl, or new sdl ?)

@kas1e

well i use the onboard via chip, the only issue i had was because i wasn't selecting "unit0" in ahi prefs so some apps wouldn't play the sound at all.

I use the regular OS4.1 installation, with the 2 updates on hyperion's website (ide and sdk related).

@SoundSquare

Hm, SDK related or SDL related updates ? It is possible that SDK update have inside some new libs/files for system intself which can solve this problem ?

ps. which gfx card for you btw ?

ps2. i made a 20minute video (50mb) which show how os4 on peg2 works (some progs,etc), and you can for sure check it and detect these strange 'beeps' for example on 09:32 of time (some shooter game), or for example on 13:37 (on 'giddie' game). Pretty noise sound :)

@SoundSquare??
One more question: if you run MilkiTracker, then choice a module, press "play it", and when try to moview window of Milky fast - will you hear some 'ahi' surrenders ? A little noise sounds ? (not these 'beeps' about i talk, but just some 'slowdowns') ?

Also, can you please put the full list of your SOBJS: directory with size of files, etc. Maybe some bad lbrary for me ..

@kas1e

Milkytracker on my system has the same behaviour - I still don't know what's causing it, it's one of the bug I hope to address for the next version of the tracker.

@Varthall

Peg2 for you ? It's not only "Milky" related. The same for example with "Protrekkr". Same for you ?

Looks like these thinks (ahi behaviors when move window) and 'noise beeps' in SDL apps are different ..

@all

ok! Looks like i found where is a bug!

If i use any screen mode with 32 bit - i will have always in SDL apps these 'noise beeps'. If i use 16bit screen modes (does not matter which one by size, 640x480 or 800x600 or 1024x768) - all is ok!

The problem exactly when i have 32bit modes in workbench. Any idea what i need to check/set/add for make it works with 32bit screens ? Some 'refresh' problem thinks ? Like need right values into p96 setup ?

@vathall
Also problem with Milky are gone too, if i have 16bit screen mode for wb. All of this looks like like somethink must be setuped for screens for p96 i think ..

@kas1e

Same here, the audio slowdowns disappear when selecting a 16bit screen. I'll try recompiling Milky with the recent release of SDL, it might cure the problem.
