I have a Windows 10 HTPC with Nvidia 1050Ti card with HDMI output to a TV as monitor and to a Receiver (Yamaha RX-V765) for speaker output.
Yesterday Windows decided to not have any audio output (red x in the tray speaker icon with the message "no audio output device"). Nvidia control panel shows the receiver though, and it sends it some signal as well because if I activate/deactivate it, the 5.1 lights go on and off so it receives something. Windows display properties also show the receiver but as a second monitor, not recognising the audio output (this is a weird configuration where I have to connect the receiver as "monitor" with the lowest possible resolution but it actually is only used for the audio output of the HDMI cable - this has been working fine for more than a year, until yesterday).
When I go to device manager, the receiver (and the TV for that matter) shows there as an audio output device with no apparent error, except when I select properties/events it says device not migrated with the below details:
Device SWD\MMDEVAPI\{0.0.0.00000000}.{54fcc462-dff2-43b7-bf56-3e830a584410} was not migrated due to partial or ambiguous match.
Last Device Instance Id: SWD\MMDEVAPI\{0.0.0.00000000}.{08bf3c52-df5f-468f-b558-a8773325e14f}
Class Guid: {c166523c-fe0c-4a94-a586-f1a80cfbbf3e}
Location Path:
Migration Rank: 0xF00000000000F120
Present: false
Status: 0xC0000719
From googling it seems this is usually solved with drivers reinstallation, so I've done that several times, installing via device manager, via nvidia directly, deleted the device and installed again, and nothing happened. Today Windows Update installed the feature update to version 1903 and nothing changed (the problem didn't happen after a windows update by the way, I checked. It appeared yesterday and the previous update was a week ago, and it was working fine in between.
Any ideas?
