From 8dc5efe3d17cd572328ac4f1ebde629c83317f54 Mon Sep 17 00:00:00 2001 From: Nick Kossifidis Date: Sat, 15 Feb 2020 03:23:35 +0200 Subject: ALSA: usb-audio: Add support for Presonus Studio 1810c This patch adds support for Presonus Studio 1810c, a usb interface that's UAC2 compliant with a few quirks and a few extra hw-specific controls. I've tested all 3 altsettings and the added switch controls and they work as expected. More infos on the card: https://www.presonus.com/products/Studio-1810c Note that this work is based on packet inspection with usbmon. I just wanted to get this card to work for using it on our open-source radio station: https://github.com/UoC-Radio v2 address issues reported by Takashi: * Properly get/set enum type controls * Prevent race condition on switch_get/set * Various control naming changes * Various coding style fixes v3 improve readability of sample rate filtering and some other minor changes.
