Hi All I installed Zorin 18 core last week on my Acer laptop and all is good except sound - No input device and only Dummy output shown. The same thing happens if I boot from the Zorin live USB. Oddly though if I boot from a Linux Mint live USB the sound works fine. I've tried about 20 suggestio…

Since my last post I've been trying other kernels on my Acer Aspire 4820T. I'm now running kernel 6.15.11 which works fine. But if I move to kernel 6.16 the soundcard is not recognised again. I'll stick with 6.15.11 unless a later kernel gets the soundcard working again.

No sound input device in Zorin but works from Mint live USB

You can use the mainline installer tool to install kernel 5.15.

After the installation reboot and in grub menu select "advanced options" to select the kernel 5.15 to boot from.
