Hello:
 
Do any of you know if anyone has ever had alsa working with a digital
microphone
on a Sigmatel Codec within the Intel HAD device working; ie; a digital
microphone
only, that does not go through the normal analog input and mux?

Thank you

Mark Allyn

I think Matt Porter was working on some systems with that last year.
Not sure what happened to him, as I haven't seen any patches since early
January.  He submitted some digital mic patches against the 9205 codec
code.

I could probably whip something together for you next week.  Send me the
system specs (lspci -s 0:1b -vn and cat /proc/asound/card0/codec*) and
I'll get on it.

Tobin:
 
I was unable to load the driver on this system. There was an error
message from ALSA 
(which I sent an earlier email on the list.
 
The lspci entry for the device is:
 
00:1b.0 Class 0403: Intel Corporation 82801G (ICH7 Family) High
Definition Audio
 Controller (rev 02)
 
Here is the dmesg output from alsa when I attempted to get at the
device. Because of 
this, there is nothing in /proc/asound/card0 as /proc/asound/cards shows
no cards.

Ok, I'll look into it.  Probably a misconfiguration in autoconfig.  Your
earlier email listed this as a 9202 codec.  I'll get the documentation
and go from there.

I'll still need the pci subsystem ID though.  
lspci -s 0:1b -vn will give you that.

Tobin:

This is a STAC 9202 device.
 
Here is the lspci segment with the -vn:
 
=====================
 
00:1b.0 Class 0403: 8086:27d8 (rev 02)
        Subsystem: 8384:7632
        Flags: bus master, fast devsel, latency 0, IRQ 10
        Memory at 32340000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Capabilities: [60] Message Signalled Interrupts: 64bit+
Queue=0/0 Enable-
        Capabilities: [70] Express Unknown type IRQ 0

=====================

The following lines in the patch_sigmatel.c file (version 1.0.14rc2)
have this 
subsystem id point to the stac 925x family.

======================

        { .id = 0x83847632, .name = "STAC9202",  .patch = patch_stac925x
},
        { .id = 0x83847633, .name = "STAC9202D", .patch = patch_stac925x
},

======================

We have a Digital stereo microphone connected to the DMIC_IN r & l (pins
43 and 44)

We have internal speakers connected to PORTA

We have a headphone jack connected to PORTD and GPIO_1.

	I think Matt Porter was working on some systems with that last
year.
	Not sure what happened to him, as I haven't seen any patches
since early
	January.  He submitted some digital mic patches against the 9205
codec
	code.
	
	I could probably whip something together for you next week.
Send me the
	system specs (lspci -s 0:1b -vn and cat
/proc/asound/card0/codec*) and
	I'll get on it.

I see what the problem is.  The documentation doesn't show the digital
mic on the widget diagram for the 9202, and I haven't had any requests
for it on the 9250 series (what this code was originally written for).
The issue is that for some codecs, there is no digital mic port, so
trying to configure a nonexistent port would cause the driver to fail.

I'll get a patch worked up and send it to you as soon as possible.
