Date: Tue, 17 Feb 2009 14:00:25 +0100 From: Stefan Klug Subject: [SDL] Possible bug, paused audio playing garbage On my WinCE device a paused audio device plays random garbage. This might also be the issue in the thread "sound cracks with SDL_mixer and AUDIO_S16LSB" I don't have that much knowledge of the SDL audio part, but the attached patch fixes it for me, and collapses two redundant ifs. I'm not sure if this is the correct way to fix this. Shouldn't the complete stream conversion part of the RunAudio loop be dependent on the paused property of the device? (not only the call to (*fill)(udata, istream, istream_len). Anyways. Would be great if the patch or a fix could find its way to SVN ;-) Cheers Stefan
