From e66bc8b2a7d85166935a2da651b94efb9e7a2f11 Mon Sep 17 00:00:00 2001 From: James Courtier-Dutton Date: Wed, 6 Jul 2005 22:21:51 +0200 Subject: [PATCH] [ALSA] emu10k1: Add module option uint subsystem. EMU10K1/EMU10K2 driver It allows the user to force the snd-emu10k1 module to think the user has a particular sound card. Useful if their particular sound card is not yet recognised.
