[SOLVED] Audio pops and static on pulse audio after 4.15 upgrade

After updating to 4.15 (not sure if kernel related) I'm getting weird audio behavior, if there is no audio output after about 15 seconds there is an audible pop and then lots of quiet static noise.

Any further audio output will cause things to go back to normal, until audio is silent again for about 15 seconds, and then another pop + static.

I'm running pulseaudio on Gnome, if it matters.

Also reported on reddit - https://www.reddit.com/r/archlinux/comm … e/dtuzgjy/

Any ideas where this is coming from?

Which audio driver? snd-hda-intel? That has seen a default power save mode enablement https://git.archlinux.org/svntogit/pack … f3de#n6130

Try

options snd_hda_intel power_save=0

in modprobe.d

I'm experiencing the same problem and that modprobe.d fix didn't work for me, I'm still getting audio skips. Where can I find PulseAudio log files?

Define skips, continuous during playback? There are currently a few other issues with the kernel config that might affect audio most relevantly PREEMPT is disabled which is required for getting realtime priority. Try to update the kernel from testing or wait for it to make it to stable.

As for logs in general, they are logged in your user's journal

journalctl -b --user-unit=pulseaudio

however pulse isn't very chatty by default and might not even be able to recognize the underlying kernel issue.

I get audio skips in mpd if I'm doing something specific on Chromium. The most consistent way I found to reproduce it is by opening pictures people sent me on WhatsApp (via web.whatsapp.com), doing that always makes mpd skip the song currently playing.

I've tried to update to the kernel from [testing], but I didn't read absolutely anything about it, so I upgraded then I rebooted, but systemd got stuck at some point. But it's fine now, I chroot'd and downgraded the kernel again.

But since this issue is already being worked on, I suppose I could wait for next kernel update and then see if that fixes it.

Thanks.

For me the example from arch wiki worked:

/etc/modprobe.d/modprobe.conf:

options snd_hda_intel power_save=0
options snd_hda_intel power_save=0 power_save_controller=N
