I don't see anything either Jake. Note there's a new AppleALC out five days ago. Sure someone will pick it up shortly. Thanks; appreciate your input. Mo

@InsanelyDeepak codec_dump.txt.zipI've got a new one I believe. Detected ALC289 but some sort of crazy in the Dell Specs: ALC3281 https://topics-cdn.dell.com/pdf/precision-15-7530-laptop_specifications_en-us.pdf Codec_Dump attached from Mint. Any suggestions? Plays via VoodooHDA but headphone socket sounds overdriven and isn't auto select. Thanks Mo codec_dump.txt.zip debug_27519.zip

Jake Lo. Thanks for the reply. Good to know I'm not going mad then. I've done the best I can to this point. I'll follow up as suggested. The I2C is running in polling mode rather than via interrupt. Mo
