Hi, I’m working on hot swapping Audio output devices. Everything wokrs nice and smoothly until i re-plug the last remaining device in the system. When it’s remove i get this error: [FMOD] OutputWASAPI::mixerThread : GetCurrentPadding returned 0x88890004. Device was unplugged! After pluging it ba…

Thank you for the script. Unfortunately, 2.01 is no longer supported. Can I confirm your integration version: [image] [image] We have documentation for migrating major versions for Studio here: FMOD Studio | Advanced Topics - Migration FMOD Studio Projects . Migrating Unity versions will be aide…

Hi, Thanks for bringing this to our attention. What version of the FMOD integration are you using? Please could I get the code you are using to detect the output devices?

FMOD integration Version: 2.01.19 This is the code i use for the callback: List<string> GetOutputDevices() { List<string> devices = new(); RuntimeManager.CoreSystem.getNumDrivers(out var drivers); for (int i = 0; i < drivers; i++) { RuntimeManager.CoreSystem.getDriverInfo(…

Hey @Connor_FMOD , we have experienced this issue on version 2.02.22 as well. Could you verify that it’s also broken on your end and also perhaps give an idea about a possible timeline for a fix?

Hi, How are you detecting the device changes? Could I grab any code and reproduction steps? With the following settings enabled: [image] Could I grab the full editor logs when experiencing the issues? [image]

Our code to get the changes looks like this: [AOT.MonoPInvokeCallback(typeof(SYSTEM_CALLBACK))] private static RESULT OnFmodSystemCallback(IntPtr systemPtr, SYSTEM_CALLBACK_TYPE type, IntPtr commandData1, IntPtr commandData2, IntPtr userData) { if (type == SYSTEM_CALLBACK_TYPE.DEVICELISTCHANGED…

Hi, Thanks for sharing the code and logs. Since Connor is away, I will continue with this support case. I was able to reproduce this locally with a minimal Unity test. When the DEVICELISTCHANGED callback is registered, FMOD reports NoSound Driver after the last device is disabled, and it does not…

Hey! Thanks for the reply. Unfortunately, I don’t think that encompasses the entire situation here. The problem is not about it not detecting driver changes or swapping to the most recently connected device automatically. That we already handle as the documentation says. The problem is the method …

Thank you for sharing the extra information! [image] RegalDreamer: The problem is the method RuntimeManager.CoreSystem.getNumDrivers(out numDrivers); always returns 1 and the RuntimeManager.CoreSystem.getDriverInfo for that driver always returns the Guid.Empty driver. getNumDrivers returns t…

Hi,
That’s exactly how i checked the version.
Sadly upgrading is out of scope with current project now.
I guess we’ll have to scrap the feature.

Thanks for the information.
