alsa-project/alsa-ucm-conf issue #329 was edited from IsaacLambat:

Hello, I have recently upgraded from `alsa-ucm-conf 1.2.8-1` to `1.2.9-1` and this has caused some latency of around 1/2 seconds for outputting audio via the `Focusrite Scarlett 2i2 3rd Gen` with is connected the computer via USB. No latency is introduced when plugging wired headphones directly in to the motherboard so this 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.

Many thanks :D
