I can confirm that the audio issue is fixed with the Ubuntu mainline kernel 7.1.11.
Tested kernels: * 7.0.0-30-generic: internal audio via RT721 / AMD SoundWire does not work. * 7.1.11-070111-generic: internal audio works correctly. With 7.1.11, the RT721 SoundWire devices are properly exposed as an ALSA sound card: ``` $ uname -r 7.1.11-070111-generic $ aplay -l card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] card 0: Generic [HD-Audio Generic], device 7: HDMI 1 [HDMI 1] card 0: Generic [HD-Audio Generic], device 8: HDMI 2 [HDMI 2] card 1: amdsoundwire [amd-soundwire], device 0: SDW1-PIN0-PLAYBACK-SimpleJack rt721-sdca-aif1-0 card 1: amdsoundwire [amd-soundwire], device 2: SDW1-PIN1-PLAYBACK-SmartAmp rt721-sdca-aif2-2 ``` Relevant dmesg output: ``` input: amd-soundwire Headset Jack as /devices/pci0000:00/0000:00:08.1/0000:03:00.5/amd_sdw/sound/card1/input12 ``` Audio playback through the internal speakers is working normally with 7.1.11. So this appears to be a kernel-side issue that has been fixed upstream between Ubuntu kernel 7.0.0-30 and mainline 7.1.11. I can provide additional dmesg / ALSA information from both kernels if needed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163094 Title: ASUS Vivobook S16 M3607GA: internal audio missing with AMD ACP7.x / RT721 SoundWire To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2163094/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
