Created attachment 1544911 [details] TXT file generated by alsa-info.sh Description of problem: I've installed a fresh Fedora 29 installation. I didn't connect to any wi-fi router until I was logged in for the first time, wishing to do a 'sudo dnf upgrade'. When I connect to any wi-fi router, as soon the network traffic starts I hear a static sound coming from the speakers, that seems to be synchronized with the traffic. It is not continuous. Let me give you an example: 1) connect to a wi-fi router; 2) open firefox; 3) type any valid url; 4) static sound starts as the page loads; 5) static sound disappear as the page finishes loading. Another example: 1) connect to a wi-fi router; 2) open terminal; 3) type 'sudo dnf upgrade'; 4) static sounds starts as the dnf downloads data; 5) static sound disappear as the download finishes. The same occurs if I turn off wi-fi and connect an ethernet cable. But there's something weird. Static sounds disappear (even with intense network traffic) if I go to Settings>Sound. While I'm on the "Sound" tab, static sounds do not occur, whatever I do. But when I leave the Sound tab, while having network traffic, the static sounds starts after exactly 6 secs (I did it multiple times to check it). What did I do until now: 1) followed the instructions in https://fedoraproject.org/wiki/How_to_debug_sound_problems 3) removed alsa-plugins-pulseaudio with dnf 4) searched my subsystem number on the internet for "'17aa:367b' alsa" but didn't find anything relevant 5) did the "alsa-info.sh --no-upload" command and uploaded the txt here. 6) opened this bug thread With all the steps above, I still have the same issue.
Some notes I forgot to include and had tested: 1) having network traffic while playing a video on youtube doesn't make the static sounds, even if the youtube video is muted. It seems that while there's an application using the sound, I don't have the problem. When I close the youtube video, the static sound comes back (while there's network traffic). It works the same way with rythmbox. But with rythmbox I need to play a file for static sounds go away. 2) muting all the devices on alsamixer doesn't help either. 3) I think the hardware is ok. When I boot Windows (I have it on dual-boot) or ubuntu (live-usb) I don't have these issues.
Could you also attach output from 'alsa-info.sh --no-upload' from ubuntu (live) ?
Sure.

Probably it's the power save function. Ubuntu has this option off: ... !!Loaded sound module option ... - power_save : 1 + power_save : 0 ... Try this command sequence as root (note that it will reboot your machine): echo "options snd_hda_intel power_save=0,0" > /etc/modprobe.d/alsa-hda.conf reboot
That works. Thank you! Anyway, will updating the system or upgrading it in the future undo this fix? Do I need to do it every time? Or can you guys make it default so people with the same hardware as me won't have to deal with it in the future? Again, thank you for this! I'm really happy right now =)

Created attachment 1545799 [details] alsa-info kernel 4.20.16-200.fc29.x86_64 Since update, my sound card was removed. Now I got no sound at all.
Actually, all the Kernels I have (since 4.18, that was included within the oficial ISO) don't show any sound card.
It was my fault. The power_save cannot be set per card, so replace the modprobe config: echo "options snd_hda_intel power_save=0" > /etc/modprobe.d/alsa-hda.conf reboot
Oh... Ok. Now is working. Thanks.
