Hello, I'm new to this forum but you all seem very knowledgeable and I'm stumped here. Maybe someone here can think of a new fix to try.
My trouble is with the sound (Realtek ALC4080) on a new motherboard (MSI z590 Torpedo) motherboard on a (mostly) new PC
build.
Using the TOSLINK audio output, the sound will work normally for some time but suddenly and randomly the sound will cut out and a very loud hissing sound is output instead. It happens randomly and sporadically. Some days it won't happen at all, other days it happens several times every hour.
Any thoughts on what I can I do to make this audio output behave normally? Do you think it's a hardware problem or a driver issue?
Some notes from testing and research:
- Issue does not occur with any other audio outputs. TOSlink only.
- Tested, confirmed that the cable is not the cause.
- Tested, confirmed that the receiver is not the cause.
- Found several threads about this issue with the alc4080 on motherboards from a variety of manufacturers but I haven't found word of a fix.
- (It seems incredibly common for forum-posters to suggest "just buy a sound" card but that's a distraction from the issue at hand.)
Here's what I've tried so far:
- Windows, Windows Update, BIOS, and Drivers are all latest versions. Drivers via manufacturer.
- Tried resetting the CMOS but it didn't help
- MSI support suggested to disable Intel C State in the BIOS, but it didn't help. (Their other emails are poorly written to the point of futility.)
- Realtek support did not respond to my question.
