From: Frederic Popp Date: Sun, 8 Mar 2026 15:22:16 +0000 (+0100) Subject: ALSA: usb-audio: add Studio 1824 support X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c4791ce96b88a444b04c7089ae2827a3b3ae1877;p=thirdparty%2Fkernel%2Flinux.git ALSA: usb-audio: add Studio 1824 support Adapt the already implemented support for the Studio 1824c audio interface to the predecessor Studio 1824. Basically just a change adding the different hardware ID in the relevant places. Tested as much as possible. All implemented functionality seemingly works.
