So I heard that the zenbook 13/14 don't have any audio on linux, but then I found some reddit comment saying that a kernel update fixed it. Anyone here who uses one and can confirm that?
You need to post your model #, or at least year and chipsets. ASUS releases refreshes every uear. Your current kernel version would be helpful as well.
I have a newer Zenbook and can confirm when I first got it, and wiped windows to put Ubuntu on it, audio didn't work from the speakers. Headphones worked just fine. There's a blog from some Asus dev community documenting the issues and resolution. I'm on mobile right now and can't find it. I can confirm it was addressed on Fedora a few kernel releases back though and that all is well. I'll post the blog link shortly. Per post above please provide your model number.
2023 14-inch oled i5 here. there was an easy fix for no audio on speakers, a udev drop-in iirc. it's been an awesome machine all round. on mobile now but i might post a link later.
Looks like the fix is likely already in the kernel. Patches have been submitted towards the end of December 2023. Remember this won't help if you use an old kernel (Arch, BTW, has the latest :o)
I have a Zenbook 13 (model UX331F), bought new right around the start of COVID. Installed Linux Mint maybe 6 months ago, audio works just fine, and I didn't have to do anything special, it just worked right out of the box. I had tried Pop_OS before Mint and I don't remember any audio issues there either.
I use a Zenbook 14 (an old one though from 2017) and I've not had audio issues on fedora since I made the switch to Linux last year. One thing I do still have issues with is sometimes it fails to sleep/suspend correctly. This isn't a consistent issue though and it seems to be a gamble on if each update will fix it or make it worse. Still not been a big enough issue to make me stop using Linux.
But yeah to answer your question, I've had no audio issues on my Zenbook 14 (other than a slight popping type noise when audio starts playing when I use headphones)
bind a hotkey to suspend. If I hit that, let it sleep, and then close the lid then it's pretty certain that the laptop is really asleep.
Editing much later - 2 only worked accidentally. The real fix is to kill bluetooth before suspending. 2 worked because Bluetooth wasn't able to come back up in time for the 2nd suspend attempt.
