Hi, I need to disable the thunderbolt power supply . I have a Sonnet Echo III with a RME sound in it and I have sound buzzing.
I test the thunderbolt Echo III on mac and when the macbook is on DC power the buzz is gone.
So I'm sure now that it's coming from the thunderbolt power supply of the motherboard.
Thank in advance for your help.
There may not be a universal solution for disabling Thunderbolt power supply on all systems, as it often depends on the specific motherboard and BIOS/UEFI options available. However, I can provide general guidance that may help you find the relevant settings. Please note that newer BIOS/UEFI versions may have additional or different options.
Here are some steps you can take:
Look for Thunderbolt Settings:
Power Delivery Settings:
Contact Manufacturer Support:
Check Operating System Settings:
Keep in mind that making changes to BIOS/UEFI settings carries some risk, and you should proceed with caution. If you're not comfortable doing this yourself, seeking assistance from someone with experience or contacting the manufacturer's support is a good idea.
