Subject: [PATCH] drm/bridge: lontium-lt9611uxc: disable audio capture for HDMI card
Date: Wed, 3 Sep 2025 02:18:18 +0300 [thread overview]
Message-ID: <20250902231821.2943-1-vovchkir@gmail.com> (raw)
The LT9611UXC only has an I2S input and therefore only an HDMI-TX
audio channel. In this case, the capture channel must be disabled
on the HDMI sound card.
