Subject: Intel HDA pin-config values (patch_sigmatel.c) - Dell Inspiron 1721 (also 1521?) mic
Date: Sat, 11 Aug 2007 16:24:33 +0100	[thread overview]
Message-ID: <46BDD4B1.7030507@gmx.de> (raw)

Hi,

I am wondering where the values of ref9205_pin_configs in patch_sigmatel
come from. The SigmaTel documentation gives different reference values for
the 9205.
The set of values I use at the moment is
static unsigned int ref9205_pin_configs[12] = {
	0x02214020, 0x02a19041, 0x40000100, 0x40000100,
	0x40000100, 0x40000100, 0x40000100, 0x40000100,
	0x10a000f0, 0x50a000f0, 0x01441030, 0x01c41030
};
(the first two are actually from the SigmaTel document, the other just mute
the remaining in/outs)
These numbers actually work quite well for the Dell Inspiron 1721 (and
probably for the 1521), even the mic input works - although the quality
could be better and the input levels have to be adjusted carefully.
Can anybody confirm this?
Thorsten.
