Title:
Internal microphone not working on
I just updated the BIOS to the latest 7VCN46WW (Jan 2019).
Tried to boot without the `ivrs_ioapic[32]=00:14.0` kernel parameter, and the
stock 4.18.0-16-generic kernel just wouldn't boot at all.
Added the parameter back and it works.
I have to note though that although the touch pad works, I
The dumb thing is: it was working! For a while.
Then I updated the BIOS to the 1/2/2019 7VCN46WW version to see if the
`ivrs_ioapic` parameter was still required for the touch pad issue, and
now the microphone stopped working again! :(
Using the stock cosmic 4.18.0-16-generic kernel.

Yes, that works for me too! Thanks Kenji! Stock 4.18.0-10 kernel with
`noapic` removed and `ivrs_ioapic[32]=00:14.0` added to the kernel

timeout error has disappeared from dmesg.
I have a couple of issues left:

I tried the 4.15.0-39 kernel. It still doesn't work but there's a
difference in the dmesg output, which I attached. This message is new /
different:

This kernel did, as before with other 4.15 kernels, fix the microphone input
Unlike FF8Jake, I do have touchpad references in the output.
Is this the same laptop FF8Jake? Or what model laptop do you have?

If I could do that I'd fix my problem myself. I thought reporting a bug
was so people who know how to do these things could take a crack at it.
But it seems there's no one at Canonical who knows about these things
either.

All that seems to happen here is that you make me try new BIOSes and
kernels as they come out. Disappointing.

I updated the BIOS. This allowed me to remove the "pcie_aspm=off" and
"pci=noaer" kernel parameters. The others are still necessary though.
Removing "noapic" makes the system hang on boot (after the initial RAM
disk message I think, so I don't know how to get any data on what that's
all about).
Well that didn't work. apport-collect complains I am running a mainline
kernel and should report it upstream. So here's just the output of
dmesg.

Still doesn't work with this kernel. Did you make any changes to the
i2c_designware? This error still exists and I wonder if it's related
since this is a I2C touchpad.
I'm sending new logs with this kernel using ubuntu-bug below.
