From 68bffc607f7f0414fee77fa481d9c133ce0798e9 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 9 Nov 2009 22:11:29 +0100 Subject: [PATCH] sound: include ALSA sound card id in /dev/snd/by-id/ links If two USB sound cards that have the same serial number are plugged in make sure the by-id/ device node symlink is unique at least during runtime, by including the ALSA card id in the symlink name.
