From d0ec95fe6a8d9c7da6f9ff885cecbe7e328e2a2e Mon Sep 17 00:00:00 2001 From: Mihail Zenkov Date: Fri, 22 Feb 2013 17:59:38 +0000 Subject: [PATCH] ALSA: emu10k1: Allow to switch hardware sampe rate on EMU Commit 57e5c63007955838043e34c732d224b2cbbb128f "emu10k1: allow to disable the SRC" force hardware use only one rate (48000 hz). EMU 0404/1010/1616 have support two hardware sampling rates (44100 and 48000 hz). This patch add check if we have EMU 0404/1010/1616 and choose correct sample rate to restrict.
