* HDA Intel ALC889A optical spdif input on MacBooks @ 2017-04-04 22:02 René Rebe 2017-04-21 16:37 ` HDA Intel ALC889A optical optical spdif in René Rebe 0 siblings, 1 reply; 11+ messages in thread From: René Rebe @ 2017-04-04 22:02 UTC (permalink / raw) To: alsa-devel 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.

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

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 :-/ René > 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

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.

I plugged the fibre into a MacPro2,1 that we otherwise use as file server and such.

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). johannes _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel ^ permalink raw reply [flat|nested] 11+ messages in thread

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, … René -- ExactCODE GmbH, Lietzenburger Str. 42, DE-10789 Berlin DE Legal: Amtsgericht Berlin (Charlottenburg) HRB 105123B, Tax-ID#: DE251602478 Managing Director: René Rebe http://exactcode.com | http://exactscan.com | http://ocrkit.com | http://t2-project.org | http://rene.rebe.de ^ permalink raw reply [flat|nested] 11+ messages in thread

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. > 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, … me too :) I don't even remember the specs of these chips etc. johannes _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel ^ permalink raw reply [flat|nested] 11+ messages in thread
