[alsa-devel] HDA Intel ALC889A optical spdif input on MacBooks
Hi,
recently I wanted to connect my low noise mic pre-amp via optical spdif to a spare "10 year” old MacBook or MacBookPro. Those indeed have a optical input in the 3.5mm headphone jack. On macOS this also works and works as expected.
On Linux, however, no matter what I do I only get zeros when recording the -D iec958.
In /proc I see 3 capture sub-devices, where the 2nd is labeled:
# cat /proc/asound/card0/pcm1c/info ... id: ALC889A Digital name: ALC889A Digital ...
The behavior is the same on booth the MacBook as well as the MacBook Pro with either of those PCI devices:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
I have the feeling there could be some auto sensing be involved, as in the macOS system preferences I see the input switching from Mic to Optical Input as soon as I plugin in an active fibre.
As I’m not familiar with this Intel HD stuff, any hint how to start analyzing and poking this mystery would be highly appreciated.
Best regards, René
Hello again,
so I checked the MacBook schematics and it looks like the optical input should be directly connected to pin 47 (GPIO3/SPDIFIN)
Maybe EAPD get’s accidentally / wrongly enabled? - Maybe someone can point me how to double check this in ALSA?
For the record - I try to record: # arecord -D iec958 -f dat -c 2 > rec.wav Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
but only get zeros:
# hexdump rec.wav 0000000 4952 4646 0024 8000 4157 4556 6d66 2074 0000010 0010 0000 0001 0002 bb80 0000 ee00 0002 0000020 0004 0010 6164 6174 0000 8000 0000 0000 0000030 0000 0000 0000 0000 0000 0000 0000 0000 * 0304020 0000 0000 0000 0000 0000 0000 030402c
As far as I can see the right sub-device is running:

# hda-verb /dev/snd/hwC0D0 0x14 0x70C 0 nid = 0x14, verb = 0x70c, param = 0x0 value = 0x0 # hda-verb /dev/snd/hwC0D0 0x15 0x70C 0 nid = 0x15, verb = 0x70c, param = 0x0 value = 0x0
which made no difference either, and the ALC889 spec reads “when pin widget SPDIF-IN is not connected via the programming configuration register.”
Could that be a missing bit?
Any pointer or verbs I should poke welcome :-/

For the record - I try to record: # arecord -D iec958 -f dat -c 2 > rec.wav Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
but only get zeros:

Hi,
recently I wanted to connect my low noise mic pre-amp via optical spdif to a spare "10 year” old MacBook or MacBookPro. Those indeed have a optical input in the 3.5mm headphone jack. On macOS this also works and works as expected.
On Linux, however, no matter what I do I only get zeros when recording the -D iec958.
In /proc I see 3 capture sub-devices, where the 2nd is labeled:
# cat /proc/asound/card0/pcm1c/info ... id: ALC889A Digital name: ALC889A Digital ...
The behavior is the same on booth the MacBook as well as the MacBook Pro with either of those PCI devices:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
I have the feeling there could be some auto sensing be involved, as in the macOS system preferences I see the input switching from Mic to Optical Input as soon as I plugin in an active fibre.
As I’m not familiar with this Intel HD stuff, any hint how to start analyzing and poking this mystery would be highly appreciated.
Best regards, René

Hello again,
so I checked the MacBook schematics and it looks like the optical input should be directly connected to pin 47 (GPIO3/SPDIFIN)
Maybe EAPD get’s accidentally / wrongly enabled? - Maybe someone can point me how to double check this in ALSA?
I the meantime I finally figured out how this debug verb setting should work via:
# hda-verb /dev/snd/hwC0D0 0x14 0x70C 0 nid = 0x14, verb = 0x70c, param = 0x0 value = 0x0 # hda-verb /dev/snd/hwC0D0 0x15 0x70C 0 nid = 0x15, verb = 0x70c, param = 0x0 value = 0x0
which made no difference either, and the ALC889 spec reads “when pin widget SPDIF-IN is not connected via the programming configuration register.”
Could that be a missing bit?
Any pointer or verbs I should poke welcome :-/
Well, from the codec POV, the SPDIF in is straightly connected from the pin to the audio in widget, so there should be no special thing there. The possibly missing setup is the vendor-specific things, and Apple has been implementing the stuff always in a wild manner, e.g. doing via VREF, GPIO or whatever.

For the record - I try to record: # arecord -D iec958 -f dat -c 2 > rec.wav Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
but only get zeros:

Hi,
recently I wanted to connect my low noise mic pre-amp via optical spdif to a spare "10 year” old MacBook or MacBookPro. Those indeed have a optical input in the 3.5mm headphone jack. On macOS this also works and works as expected.
On Linux, however, no matter what I do I only get zeros when recording the -D iec958.
In /proc I see 3 capture sub-devices, where the 2nd is labeled:
# cat /proc/asound/card0/pcm1c/info ... id: ALC889A Digital name: ALC889A Digital ...
The behavior is the same on booth the MacBook as well as the MacBook Pro with either of those PCI devices:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
I have the feeling there could be some auto sensing be involved, as in the macOS system preferences I see the input switching from Mic to Optical Input as soon as I plugin in an active fibre.
As I’m not familiar with this Intel HD stuff, any hint how to start analyzing and poking this mystery would be highly appreciated.
Best regards, René

Hello again,
so I checked the MacBook schematics and it looks like the optical input should be directly connected to pin 47 (GPIO3/SPDIFIN)
Maybe EAPD get’s accidentally / wrongly enabled? - Maybe someone can point me how to double check this in ALSA?
I the meantime I finally figured out how this debug verb setting should work via:
# hda-verb /dev/snd/hwC0D0 0x14 0x70C 0 nid = 0x14, verb = 0x70c, param = 0x0 value = 0x0 # hda-verb /dev/snd/hwC0D0 0x15 0x70C 0 nid = 0x15, verb = 0x70c, param = 0x0 value = 0x0
which made no difference either, and the ALC889 spec reads “when pin widget SPDIF-IN is not connected via the programming configuration register.”
Could that be a missing bit?
Any pointer or verbs I should poke welcome :-/
Well, from the codec POV, the SPDIF in is straightly connected from the pin to the audio in widget, so there should be no special thing there. The possibly missing setup is the vendor-specific things, and Apple has been implementing the stuff always in a wild manner, e.g. doing via VREF, GPIO or whatever.
Did you check anything in this proc file codec setup I posted?
As far as I can see on schematics for the MacBook (e.g.. google returned a APPLE_M42C_FA522_Macbook.pdf) the optical module RX output seems to be “directly" attached to the codec’s spdif-in pin.
Yet on both, the MacBook as well on the MacBook Pro I found no way to get any digital input captured. The same setup works when booted in macOS, as well as when I plug in my digital audio source into my aging maudio delta 1010, with Linux, which, however, I do not want to continuously use for this setup, …
It’s a pity, I don’t think there are so many other laptops with optical input :-/

For the MacBook Pro I googled the i/o board schematics (820-2273 LIO.pdf) - unfortunately some lines are crippled / strange rectangles. However, it most likely spdif-in is directly connected like in the MacBook. The schematic calls the codec a ALC885 instead of the ALC889A as indicated by ALSA, … And the schematic labels the codec spdif innput pin SPDIFI/EAPD/MIDI-I/DMIC-R. However, the public ALC885 spec has a footnote “MIDI function is not supported as pins 46 and 48 are assigned as S/PDIF IO” and for the DMIC: “pin 47 can be configured to support a secondary digital mic input (DMIC-R). It is supported via a customized Realtek driver”
It is not getting better, …

Hello again,
as it is Sunday I thought it is a good time to further play with this annoying optical in issue. I plugged the fibre into a MacPro2,1 that we otherwise use as file server and such. Unfortunately ALSA indicates the same Realtek codec is used on it:
Chip: Realtek ALC889A
And, no surprise, capturing something on it:
arecord -D iec958 -f dat > rec.wav
yields nothing useful. Interestingly it yields not zeros, but another static pattern:
# hexdump -C rec.wav 00000000 52 49 46 46 24 00 00 80 57 41 56 45 66 6d 74 20 |RIFF$...WAVEfmt | 00000010 10 00 00 00 01 00 02 00 80 bb 00 00 00 ee 02 00 |................| 00000020 04 00 10 00 64 61 74 61 00 00 00 80 1b 08 1b 91 |....data........| 00000030 1b 08 1b 91 1b 08 1b 91 1b 08 1b 91 1b 08 1b 91 |................| * 00088020 1b 08 1b 91 1b 08 1b 91 1b 08 1b 91 |............| 0008802c
As I said before, according to the slightly mangled MacBook schematics the spdif pin at least on those looks directly connected with the optical receiver module.
Any tip of to debug this in the Linux driver would be welcome!
Also, I powered up the G5, to my surprise the ALSA sound-by-layout module does not even have spdif capture controls for that at all, (yes, the G5 also has optical in and out) … :-/
So in total about everything I could find around me has non working optical input with the ALSA drivers, …

Hi there,
I noticed digital input would not show up at all on my PowerMac G5 11,2, I see this in dmesg:
[ 15.719952] snd-aoa-fabric-layout: Using PMF GPIOs [ 15.720519] snd-aoa-fabric-layout: can use this codec [ 15.760567] snd-aoa-codec-onyx: attached to onyx codec via i2c [ 15.760745] snd-aoa-fabric-layout: platform-onyx-codec-ref doesn't match! [ 15.760748] snd-aoa: fabric didn't like codec onyx
and poking around a bit more I found a “topaz” codec apparently some Crystal Semiconductor CS84xx “Topaz” (S/PDIF digital input) showing up nowhere in the ALSA sources.
Am I overlooking something, or was this lost in merging? Any hint would be appreciated.
René

Neither, it was simply never implemented.
I believe that in the past ~11 years since this got merged I *still* haven't gotten any other hardware that had optical output, so I don't think I could possibly test it :)
Also, it's not as simple as output because there has to be clock recovery etc. and I never could understand how alsa would handle that.
Anyway, that's all I remember. I still have the G5 powermac, but it's never powered on any more (I used to still use it for big endian testing, but our latest HW generation makes the PCI-E bus in the system unhappy enough that it won't even boot).

Ouhm, a pity. Guess that it took ~11 years for someone to notice is an indicator of the percentage of users using the digital in ;-)
You could plug a cable from the output to the input for testing, no?
As I’m not familiar with the ALSA driver I guess I would rather spend a whole month or so trying to copy and paste something together, …

I think two or three people may have noticed before ;-)

I don't think it can - the whole clock stuff would probably not work right. If you're using the input then the whole thing must be synchronized to the input clock, and then the output also uses that clocking IIRC, so if you hook them together you don't really test the whole thing.

me too :) I don't even remember the specs of these chips etc.
