No latency is introduced when plugging wired headphones directly in to the motherboard so issue seems to be isolated to the device. I noticed the change logs indicate better support for this device was added in this version (which is great!) so these changes may have affected the existing settings of the headphones. I have downgraded only `alsa-ucm-conf` to `1.2.8-1` and the output has no latency so I am using this as a workaround. I use PulseAudio with ALSA on Arch Linux. Versions: ``` alsa-card-profiles - 0.3.71 alsa-lib - 1.2.9 alsa-ucm-conf - 1.2.9 alsa-utils - 1.2.9 pulseaudio - 16.1 Arch Linux - 6.3.9-arch1-1 ``` dmesg detects the product as `Scarlett 2i2 USB` Please let me know if any more information is needed (such as logs or config files) and if there is anything I should try.
