Hello there, As stated in the subject, the SPDIF light on the machine is always on, and this is only when I boot into Linux. Output from alsa-info: http://www.alsa-project.org/db/?f=29b57d6465130b92dd70360150aad528cfb85f92 I can get both the internal audio + headphone jack to work by editing /usr/share/pulseaudio/alsa-mixer/paths/iec958-stereo-output.conf and adding: [General] description = Headphones + Digital Output (S/PDIF) Infront of the [Element IEC958] switch = mute section. Other specifics: lsb_release -a : No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04 LTS Release: 18.04 Codename: bionic pulseaudio --version : pulseaudio 11.1 aplay --version : aplay: version 1.1.3 by Jaroslav Kysela <perex@xxxxxxxx> _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
