Coming back from Pop!_OS 18.10 (Based on Ubuntu 18.10, 4.18.0-10-generic) Still haven't tried with Audacity, but gnome-sound-recorded and Telegram Desktop have been fixed in my case.
All I did this time was setting default-sample-rate = 48000 on /etc/pulse/daemon.conf and restarting (Probably restarting pulseaudio is enough). before this, trying to send an audio recording through Telegram would end in an "muted" audio. Now it's working perfectly. You can try with arecord arecord -f cd -d 10 test.wav -> For recording aplay test.wav -> For playing (Probably gonna end up in noise) arecord -f cd -d 10 -r 48000 test-mic.wav -> recording with the 48000 sample rate should provide good results PD: Remember to increase a bit the mic volume from the sound settings -- 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.
