I've found a fix Add:
options snd-intel-dspcfg dsp_driver=2 To /etc/modprobe.d/alsa-base.conf and reboot At first audio was playing at the incorrect rate (low pitched) which I think is an ACPI issue. Going into the bios and saving then exiting and letting Ubuntu boot up and audio is returned to normal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958410 Title: bytcr_rt5640 sound not working with kernel >= 5.13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-hwe-5.13/+bug/1958410/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
