Lenovo Thinkpad E595 IRQ #7 And ACP Audio problems
Hi,
I am using my new thinkpad e595 with linux mint and kernel 5.3.0-45.In dmesg i have 2 questions to ask.
First one is "irq 7: nobody cared (try booting with the "irqpoll" option)" error.I have searched online but a few results came in.Second one is "snd_pci_acp3x 0000:05:00.5: Invalid ACP audio mode : 2" sometimes headphone jack is not working i have to reboot to properly work.Other than this 2 issues system boots and runs fine.Here i am attaching all logs to diagnose it.My cpu is AMD 3700U with vega 10 graphics.I already tried with kernel 5.6.1 and still same results.
Distribution: debian, lfs, whatever else i need in qemu

As always with new hardware we're usually on our own.
As a general troubleshooting: Do live distros work? If not, did you buy the lappy with windows onboard? Does that work without troubles?
Are there any BIOS options for sound card maybe, besies on/off, anything related to it at all?
Thanks for your reply.
Live distros i have triedebian 10 Ubuntu 19.04 MX Linux etc.None of them worked except Mint 19.3.I have bought my laptop with freedos only but i installed windows 10 when i first buy it.In windows everything working fine but my main prupose to work with linux.It seems i have a new release from Linux Mint 20 in end of this month.
In BIOS nothing is releated with sound.

as bad as it may sound, end users are the main reason we have linux drivers being created/updated today... i would consider filing a bug to your distro and linux itself.

Yep, he has sound troubles. Is it related to irqpoll suggesion from kernel idk. Depends on if it appears regardless of sound issues , that is, on every boot.
Sorry, do you have an actual problem or are you just worried by these messages?
What are these problems exactly?
Have you tried booting with the "irqpoll" option?
How long has the hardware been on the market? Rule of thumb: less than a year, problems with Linux are likely.
I have only sound jack problem. Sometimes it just works randomly, sometimes it works with laptop internal speaker, i mean sound comes both headphones and laptop internal speaker. Sometimes no sound on headphones and internal speaker. I have tested this on windows 10 it just works fine.I have also checked 3.5mm jack for bad contact or solder joints which are fine too, so this is not a hardware issue.I have to reboot pc every time to fix sound.
Btw laptop is brand new.
I haven't tried with "irqpoll" option.I am away from my pc now, will try it and inform you.

Me neither, but this would probably be a starting point: https://forums.linuxmint.com/viewtopic.php?t=280175
However as information on this seems to be very sparse and since you're using ubuntu fork, it makes sense to file it to ubuntu team if your attempts to get any attention fail. https://help.ubuntu.com/stable/ubunt...tu-bug.html.en or https://help.ubuntu.com/community/ReportingBugs (strangely enough this produces error 503 for me but it may be cached on google or elsewhere)
reporting it to mint may or may not be helpful as they're mostly just ubuntu packages, the process may differ slightly for mint, but in general you would need to compile all logs you can gather on this, be as precise as possible and try to provide all the data you can.
If the kernel in this particular mint version isn't ubuntu kernel then ubuntu team would not accept the report so maybe you should start with reporting it to mint after all.
Don't expect quick solution, this would go from mint to ubuntu and then to kernel, taking time along the way with people reviewing, asking for more details, etc.
It's as difficult as it may get for end user.
But since you mention it works flawlessly in windows it seems like it's not a hardware problem after all affecting linux only.
Good luck!
Sometimes it just works randomly, sometimes it works with laptop internal speaker, i mean sound comes both headphones and laptop internal speaker.
In a terminal, open 'alsamixer' and look for a setting called "Auto-Mute" and make sure it's enabled.

File it with the distro, but be prepared to be told that you did it wrong, have to provide more info, or have to go "upstream", which means the software developers.
Not the kernel unless you have proof it has something to do with it.
Hi again,
It has been a while when i last post.It seems sound issue exists only booting linux after windows 10 boot, i think windows mess it hardware somehow i don't know exactly.
If anyone interested only solution is disable built in battery on bios and plugin your ac adapter.Linux just works fine with this solution, i know it is annoying sadly.
I usually use linux instead of windows so not a big deal for me.
