Hi! Asus Crosshair VI Hero here with Linux 4.15.0-33-generic on Pop!_OS 18.04 (Ubuntu based). This problem is also affecting me, but I could fix it more or less. I'm using alsa for this specific device, so the audio control center for gnome is still usable and the DisplayPort audio (AMDGPU) is still working.
In my case all I needed to do was loading the module this way: pacmd load-module module-alsa-source device=hw:1,2 I found the corresponding device using the instructions from this web- page: https://frdmtoplay.com/gigabyte-front-panel-audio-with-linux/ It will make a duplicate entry on the audio input list of Gnome audio settings, but now recording is working for me. Once you try the command above and you verify it works, you can add it to the default.pa file of pulse settings (/etc/pulse/default.pa or ~/.config/pulse/default.pa) and add it after the hardware detection (In my case, line 58) ### Automatically load driver modules depending on the hardware available .ifexists module-udev-detect.so load-module module-udev-detect .else ### Use the static hardware detection module (for systems that lack udev support) load-module module-detect .endif load-module module-alsa-source device=hw:1,2 <---- Add this line Now with pulseaudio -k or restarting everything should be working without needing to do anything -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1764965 Title: [Realtek ALC1220 ASUS PRIME X370] Recording is very slow and plays 10x faster Status in sound-2.6 (alsa-kernel): New Status in alsa-driver package in Ubuntu: Confirmed Bug description: Recording applications (audacity, arecord, gnome-sound-recorder) record extremely slowly (at what seems to be 0,1x speed), which means that at playback the sound is played at a very high pitch and much faster than the original. To help you understand the issue, I've attached an archive containing two files recorded at the same time, one with arecord -f cd and the other with a stand-alone Olympus recorder. A video of Audacity's behavior when trying to record is also available: https://youtu.be/Fe20eQNvZVA Look at the seconds hand of the xclock and how much it is moving before Audacity is done recording one second of audio. Things I've already tried: * Purging and reinstalling Audacity * Purging and reinstalling Pulseaudio following the guide on the Ubuntu Wiki * Running audacity with this command: Exec=env PULSE_LATENCY_MSEC=30 audacity as suggested on AskUbuntu * Reinstalling Ubuntu on a new hard disk * Running audacity on a live CD (in Ubuntu version 16.04.3, 17.10.1, 18.04 daily and Xubuntu 17.10.1, 18.04) The machine is a Ryzen 5 1600 with an ASUS X370 Prime motherboard. The problem can be reproduced as follows: * Boot a live DVD of Ubuntu/Xubuntu 16.04.3, 17.10.1, 18.04 (versions I've tested with) * Install audacity via the terminal * Start recording, microphone is connected to the rear microphone jack.
