[Bug] Namco Museum Battle Collection: Major audio issues with cracking and skipping
Game or games this happens in
Namco Museum Battle Collection
What area of the game / PPSSPP
When I play the Original Games, the audio starts to crackle which causes issues.
- I have tried multiple devices to see if its the PPSSPP itself, Its an issue for every device i tried.
- I have tried every version of Namco Museum Battle Collection including all languages and still same audio issue.
- From all the other original games, Mappy is the only game that has slow audio for some odd reason
- All the Arrangement Games seem to be fine, its only Original Games.
Here is a screenshot of the Original Games.
I do not have a savedata for this because this is effected to multiple devices.
What should happen
The Original Games should not have Major audio issues with cracking and skipping. It Should have Normal audio like the Arrangement Games. This could be due to Simulating Block Transfer Effects but i doubt it. It is an important feature that is needed to run the Original Games.
Logs
I had trouble uploading a debug log but i hope this will help. PPSSPP Log.txt
Platform

Mobile phone model or graphics card
Nvidia GeForce GTX 1660 Ti with Max-Q Design

Last working version
None
Graphics backend (3D API)

Checklist
- [X] Test in the latest git build in case it's already fixed.
- [X] Search for other reports of the same issue.
- [X] Try resetting settings or older versions and include if the issue is related.
- [X] Try without any cheats and without loading any save states.
- [X] Include logs or screenshots of issue.
Your logs file didn't show much info as it only logs Error message, you should run the Debug Log.bat file to get more detailed logs.
Should i use the Lastest Git Build and run the Debug Log.bat?
Yes, preferably getting the logs from the latest dev build.
Hey so apparently, i have a log but i can't upload it, github is say not included in list
Hey so apparently, i have a log but i can't upload it, github is say not included in list
zip the log file first
Thanks for the log, not sure it's gonna help too much in this case though :/ Needs investigation for sure, I'm guessing these games do their own mixing and there's probably some obscure audio buffering issue that they run into, that normal games don't because they use the PSP's native mixer API.
True, i always thought it could be the Simulating Block Transfer Effects cause the original games need that but im not too sure, it could be due to audio with that function but im not fully sure. One thing i herd from a thread is maybe changed the audio format which could possibly help but im not sure if that would work
Hey, I was looking at other issues and pr, would this issue relate to this one by anychance? https://github.com/hrydgard/ppsspp/issues/5213
You mentioned trying other devices, more detail on that might help.
Some specific things to try:
- Try switching the audio backend from WASAPI to DirectSound.
- Enable the FPS display (set to Both), and check if it's showing < 100% at any time during gameplay.
- Enable "Show developer menu" under Settings -> Tools -> Developer tools, then during the game click "DevMenu" in the top corner. In the menu that appears, scroll down if needed and check "Show frametimes graph". Then reproduce the issue and post a screenshot with the frametimes displayed (we're looking for spikes.)
- Enable the setting "Log dropped frame statistics" under Settings -> Tools -> Developer tools, then use the info log method again to get frame drop statistics.
- Try other graphics backends than Direct3D 11, specifically OpenGL or Vulkan.
- Try enabling the software rendering setting, but only using a very recent git build not v1.12.3.
If there's no spikes, no logged frame drops, it's always 100%, and changing the backends does nothing - then this must be an emulation issue in audio mixing. But if any of these help, it may be some sort of performance issue.

It's got to be an emulation issue at this point because I've tried it on multiple devices such as android tv, windows, Linux, my android phone, through emulated devices, ect.
Well, it could be a performance problem (I mean, still a bug in PPSSPP) that's happening on all these devices. My questions are designed to ferret out a performance problem.
If it's happening on multiple types of devices like that, I wouldn't bother with the graphics backends or audio backends, but the other things are still useful.

Your right, I will try some of the specifics and get you a log for it so it could help more.
Hey so i tried all the specific things and i think i got you an infolog to help. Im not too sure if this is an info log but here is a log from the latest branch. Here is also another debug log to help too. InfoLog InfoLog.zip DebugLog DebugLog.zip
Hey so i just wanted to come back and check on this, did this information help you guys out on this bug?
Hey so its been a few days and i wanted to see how this is going, any new information on this by anychance?
I tried DigDug (got 60/60 FPS) and the sound aren't much different than what this video had (using JPCSP i think, may be they had similar issue to PPSSPP) https://www.youtube.com/watch?v=80c_3ju2txM It should probably sounds like this on PSP https://www.youtube.com/watch?v=Zeqq8tP3sEI
While the sound on a PlayStation version is a lot better based on this video https://youtu.be/yK48czSNEgs?t=1195
And also, DigDug II (original) sounds much better (i didn't heard any noises/crackling sound) than DigDug (original) on PPSSPP, as long you can get full speed 60/60 FPS
Hey guys, i know its been almost a month and i understand if you guys are busy with other issues but any information on this one by anychance?
Well, unfortunately the log didn't help outside iirc showing a couple drops from using software rendering. You didn't mention any of those settings having an impact, so it probably is some uncommon api usage that'll need to be investigated. I just double checked though and it is using sceSas (although mono atrac3+), so doesn't look too crazy.
Maybe it's doing something evil mucking with the actual Sas structs and double buffering. Hopefully not.

Awww thanks for telling me, I wish there was a way to fix the audio for the old games. Idk why audio is messed up, slow, fast, it could be just rendering but again, not too sure
Thank you tho.
I was wondering about this as well, glad this is on the v1.17.0 milestone tho. Thank you
Hey there, been awhile sense I responded to this issue but is ppsspp already past the 1.17.0 milestone? Its probably been about 2 years and im surprised this is still an ongoing issue.
1.17 is the upcoming milestone, we're not past it.
And please don't post just for updates. I have looked at it a couple of times and haven't been able to figure it out. I will look again but no guarantees I'll solve it before the 1.17 release.
Feel free to help debug it.
Hey sure and it's totally fine. I think awhile back, it had something to do with the audio format but I'm not too sure. Maybe I will look into this more and help with debugging soon.
Thank you
@Goldenfreddy0703 Can you record the cracking and skipping (include graphic and sound) into https://www.youtube.com (and share the link with us) ?
