Hi, me again yep XD. I dont know why but all times I make custom wavs/mp3 for portal 2 it says the same in the console and not play...: [Sound] S_StartSoundO: Failed to load sound 'glados secret\glados\glados_start_01.mp3' . Can't create mixer.

I dont know what I need to make custom sounds for portal 2, I tried with many tutorials and nothing ._.

I can upload the audio file if its necessary... in mp3 is 128kbps, in wav is stereo 1411...

Can some one help me please? T.T

Edit: now it says the same except cant create mixer... now it says file is missing from disk/repository

FIXED!: I dont know why but with the ingame command snd_rebuildsoundcache it works O.o. But now I dont know if it will work for my friends...

I have same "can't create mixer" error. It would be nice to find a way to fix it (instead of that console command) :/

Make the sound wav with 22.500 and use the command build_soundcache, later, if you want to have your sounds in your map, you need to pack with your bsp.

Problem is that the sound file is 4 minute long so it gets too big. I would rather use mp3 format.
