No Speaker Audio on Acer CP713-2w Brunch: r110 20230310

[garyaburns]

I just wanted to start out by saying thank you to everyone that has worked so hard to get Brunch where it is today. It is truly amazing to see all the hard work and effort that many have put into building something that is great.

I have been wanted to dual boot my Acer Chromebook CP713-2W with Windows10/11 and ChromeOS for a few years now, and I am finally very close to have both up and running.

Here is what I currently have installed: Chromebook: Acer Chromebook Spin CP713-2W CPU: Comet Lake 10th Gen i5-10210U 1.6GHz BIOS: Mr Chromebox 4.19 Chrome Image: Chromeos_15329.44.0_hatch_recovery_stable-channel_mp-v6.bin Brunch: r110 20230310 Kernel: chromebook-6.1

From reading other post: Running the "cras" command from the Chromeos shell comes back with nothing.

I have the volume slider showing within ChromeOS and it shows an Output of Speaker (internal). Just so sound coming out of the speaker. Any help would be greatly appreciated. I am a newbie to ChromeOS so please be patient with me and I will get you whatever information that may be helpful. Thank you once again.

Sound should work if you use the following parameters: Recovery: hatch Kernel: 4.19 Option: native_chromebook_image

Unfortunately using the settings provided did not work. The Speaker and Microphone were not even detected in that configuration and the Wifi, backlit keyboard didnt work either.
