Hi Effenberg, I've been trying your codec in an emulator with the latest upstream code, and it seems to work there, so can you please try the following:
1) Make sure you have no alsa overrides installed (make sure "modinfo snd-hda-codec" returns /lib/modules/<kernel version>/sound/pci/hda/snd-hda-codec.ko) 2) Your logs indicate a modified /etc/modprobe.d/alsa-base.conf, make sure it is unmodified 3) Install latest upstream code: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS 4) Reboot and test. This should make automute work. > However, muting any of them on AlsaMixer mutes both. Hmm, this is probably PulseAudio playing some tricks after a workaround I added for another bug. I guess we'll have to live with that for the time being. ** Changed in: alsa-driver (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/871582 Title: M4A89GTD_PRO_USB3/Realtek ALC892, Green Headphone Out, Front] Playback problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/871582/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
