From 6632d64b0b596b9588b607806ac6d36c8c2c9696 Mon Sep 17 00:00:00 2001 From: Pavel Hofman Date: Mon, 3 Dec 2007 12:44:28 +0100 Subject: [ALSA] switching rate in STAC9460 codec of Prodigy192 * support for switching rate in STAC9460 - using set_rate_val of the akm infrastructure * listing all STAC9460 registers in proc * disabling mpu401 device for Prodigy192 - otherwise the currently flawed mpu401 code hangs kernel when opening the midi device * removing old unused commented-out code Signed-off-by: Pavel Hofman Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela --- sound/pci/ice1712/prodigy192.c | 271 ++++++++++++++++++----------------------- 1 file changed, 116 insertions(+), 155 deletions(-) (limited to 'sound/pci/ice1712/prodigy192.c') diff --git a/sound/pci/ice1712/prodigy192.c b/sound/pci/ice1712/prodigy192.c index 4b21d5c1c4ff..6d81a1c61d41 100644 --- a/sound/pci/ice1712/prodigy192.c +++ b/sound/pci/ice1712/prodigy192.c @@ -81,6 +81,24 @@ static inline unsigned char stac9460_get(struct snd_ice1712 *ice, int reg) /* * DAC mute control */ + +/* + * idx = STAC9460 volume register number, mute: 0 = mute, 1 = unmute + */ +static int stac9460_dac_mute(struct snd_ice1712 *ice, int idx, + unsigned char mute) +{ + unsigned char new, old;
