ISimpleAudioVolume G/SetMute not updating
There could be several reasons why ISimpleAudioVolume::GetMute
and ISimpleAudioVolume::SetMute
are not updating. Here are a few things to check:
Verify that you have obtained the
ISimpleAudioVolume
interface for the correct audio session. Make sure that you are using the correct session ID when callingIAudioSessionManager::GetSimpleAudioVolume
. You can also try callingIAudioSessionManager::GetAudioSessionControl
with the same session ID to verify that you are indeed obtaining the correct audio session.Make sure that the audio session is not already muted or unmuted. If the audio session is already muted, calling
ISimpleAudioVolume::SetMute
withTRUE
will not have any effect. Similarly, if the audio session is already unmuted, callingISimpleAudioVolume::SetMute
withFALSE
will not have any effect.Verify that you have the necessary privileges to control the audio session. Depending on the operating system and user account, you may need to run your application with elevated privileges or obtain a specific access token to control the audio session.
Check for any error codes that may be returned by
ISimpleAudioVolume::GetMute
andISimpleAudioVolume::SetMute
. These functions returnHRESULT
values that can indicate errors such as invalid arguments or insufficient permissions.Make sure that your application is properly releasing the
ISimpleAudioVolume
interface when it is no longer needed. Failing to release the interface can lead to unexpected behavior and may prevent subsequent calls toGetMute
andSetMute
from working correctly.
If none of the above suggestions help, you may need to provide more specific details about your code and the environment in which it is running in order to diagnose the issue.
