Bug 3868

Summary: Delay after calling SDL_CloseAudioDevice
Product: SDL Reporter: Andreas <andreas.grabher>
Component: audioAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 CC: eric.t.scrivner, sezeroz
Version: 2.0.6   
Hardware: x86_64   
OS: Mac OS X 10.9   

Description Andreas 2017-10-10 06:06:19 UTC 
Calling SDL_CloseAudioDevice with valid SDL_AudioDeviceID causes a delay of multiple (> 10) seconds. The bug was not present in SDL v2.0.5. Affected machine is iMac, early 2009 running Mac OS X v10.9.5. No other hardware or OS tested.
Comment 1 Eric Scrivner 2017-10-12 18:42:00 UTC 
Can confirm and reproduce this issue on OS X Sierra. Also, can add that this only happens when AudioSpec.samples < 1024. At 1024 or higher, calling CloseAudioDevice is nearly instantaneous.
Comment 2 Ryan C. Gordon 2017-10-13 05:18:10 UTC 
This is fixed now, in https://hg.libsdl.org/SDL/rev/9658d3a4b03a ...if you have a chance, please test the latest in Mercurial, because we're planning to ship a 2.0.7 release very soon with this fix, and I'd like to know it solves your problem.

Thanks!

Comment 3 Andreas 2017-10-14 07:58:44 UTC 
Thank you, Ryan! I just compiled the latest SDL2 code and can confirm that the delay is gone.
Comment 4 Eric Scrivner 2017-10-14 19:03:52 UTC 
Ryan: Wow, thank you for the quick fix! Downloaded and can also confirm that this issue is no longer happening.
