From: Jonathan Lane Date: Wed, 11 Jun 2025 19:31:25 +0000 (-0700) Subject: ALSA: hda/realtek: enable headset mic on Latitude 5420 Rugged X-Git-Tag: v5.10.239~58 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8e56a792eba5a6b689073235d5abfa2e77949dec;p=thirdparty%2Fkernel%2Fstable.git ALSA: hda/realtek: enable headset mic on Latitude 5420 Rugged commit efa6bdf1bc75e26cafaa5f1d775e8bb7c5b0c431 upstream. Like many Dell laptops, the 3.5mm port by default can not detect a combined headphones+mic headset or even a pure microphone. This change enables the port's functionality.
