Windows Explorer freezes Audio Drivers
I am running a clean, virus and malware free windows 7 professional machine. I do QA for a company which makes recording software called Mixcraft, which you can see here http://acoustica.com/mixcraft
I have recently had an issue where opening windows explorer while the software is playing audio, will freeze the audio driver/device, causing me to have to restart the software to get playback happening again.
System specs
AMD FX 8350 8 core 4Ghz processor
16GB ram
2, 2TB drives
Nvidia gforce210
Multiple sound devices and interfaces. The issue mainly happens with a Presonus Studiolive 16.0.2
* I have ran the exact same tests with the same hardware on another win7 pro machine and do not have the issue.
* Nobody else has the issue
* The issue will happen with different daw (recording software) on the same pc, so the issue is not Mixcraft.
Things I've tried
* Disconnecting all network dirves, usb drives, etc
* Disabling all 3rd party shell extensions via shellexview
* Using asio, wav or wavert, all have the issue
* Updating everything on the pc (which i am usually up to date anyway).
* Updating firmware on the interface, along with driver
My theory about this is as follows: Something about Explorer is freezing the system, causing all system threads to stop processing, even highest-priority audio threads, like those used in Core Audio mode. For a moment, all mixing ceases.
Chances are that this ASIO driver can only wait so long for audio data before it starves and just quits. WaveRT & Wave eventually recover, but the ASIO driver doesn't.
I have attached a zipped video showing me reproducing the issue.
