jcosx69 Posted May 25, 2023 Share Posted May 25, 2023 Hello, I just move to a newer machine from my old Lenovo M73 to the more recent M70q, everything works fine except sound, when it is loading Mac os it makes a sound similar to the ones that occur when you plug or unplug an electric guitar or a microphone (a POP! with a buzzing noise), I have tested every alcid layout related to this codec ALC235, some of them do not work at all but some work with the noise problem. The machine runs with Apple HDA driver, Lilu and Whatevergreen, please does anyone knows how to fix this?. thank you in advance.

Slice Posted May 25, 2023 Share Posted May 25, 2023 I spent some time in past resolving the problem with VoodooHDA. It is special setting "Disable input monitor" absent in AppleHDA because Apple has no such audio chip.

ichelash Posted May 25, 2023 Share Posted May 25, 2023 Since we talking about Audio, i need you input on this issue i got @Slice, i have this hack that boot chime plays well with internal speakers. but after that. It doesn't work. So i just use headphones or BT.

But voodoHDA sound quality is terrible, that is why I'm with AppleHDA. 1 Quote Link to comment https://www.insanelymac.com/forum/topic/356798-pop-and-buzz-noise-at-booting-m70q-big-sur-opencore/#findComment-2805137 Share on other sites More sharing options...

The quality of modern VoodooHDA is high. 2 Quote Link to comment https://www.insanelymac.com/forum/topic/356798-pop-and-buzz-noise-at-booting-m70q-big-sur-opencore/#findComment-2805150 Share on other sites More sharing options...
