Strange behaviour in SDL2

(1/17) > >>

Jochen Schäfer:
So, I'm working on PrBoom again and I noticed a strange behaviour:
Sometimes when I start the program, there is sound. Sometimes, when I use the volume program, the sound become audible, even if I press the plus sign only once, so that the volume is going down or up one point. The direction doesn't matter.
I'm running a T480 with the newest ArcaNoae Uniaud (I also tried Paul's newer version, no change there). SDL2 is locally build copy of the most recent repo.

The question is, whether somebody knows this phenomenom and point me to some solution.

Hi Jochen

I'm using this version of PRBoom+
  https://github.com/josch1710/prboom-plus/releases/download/v2.6um-alpha1/prboom-plus-2.6um-alpha1.zip
To run PRBoom+ it is needed:
  yum install flac fluidsynth SDL2_image

I also experience a problem with the sound. The "action sounds" of the menu and the shots of selecting the menu items sounds fine on the startup, but later when I start up the game the sound is gone. If I close the game and start it over, sometimes I get the menu sound back and sometime don't. 
I made this quick video: https://youtu.be/ssjtBMSdwis

I don't see the SDL Mixer on the exe, which is the audio stuff for SDL. Maybe is some issue with flac.
I haven't added MIDI support to my system to see if the background music works.

Hi Martin,

thanks for the feedback. At least, I'm not alone.
My working copy has SDL Mixer linked, that doesn't seem to be the issue.
My current hunch is, that something in SDL2 in conjunction with PrBoom goes wrong.

Martin Iturbide:
Hi Jochen

You may already know about this, we have two distros of SDL and SDL2.
One on Netlabs rpm (I guess from BitWise Works) and the other from Digi (http://os2.snc.ru/product-SDL.html)

Maybe you would like to test a release with Digi's SDL and see if there is any improvement.  Is that what you did to don't have the issue?

Regards

No, I didn't test Digi's SDL.
Also I don't get what you mean by your last sentence.
