From e5afbfac1c47f721c6387c5f81d300f6d6c36252 Mon Sep 17 00:00:00 2001 From: Zak Date: Mon, 26 Oct 2026 13:52:31 +0000 Subject: [PATCH] conf: USB-Audio: Add Apple USB-C to 3.5mm adapter to the IEC958 blacklist The Apple USB-C to 3.5mm Headphone Jack Adapter (05ac:110a) is a headphone DAC with no S/PDIF | IEC958 connector; its only output terminal is of type Headphones (0x0302). Add it to the blacklist to prevent it being opened, so PulseAudio and PipeWire stop offering a "Digital Stereo (IEC958)" profile for it. The card name is "USB-C to 3.5mm Headphone Jack A", but card_name replaces the '.' with '_' (as with the "USB Device 0x46d_0x821" entries), so the entry has to read "USB-C to 3_5mm Headphone Jack A".
