[alsa-devel] problem with the driver for ALC3260 sound chip
Dear all,
Here a rephrase of my issue with TOSLINK SPDIF output of my Dell XPS One 2710 system running Linux.
First: I have tried other hardware with my DTS receiver and the receiver worked fine. Also I have checked the HDMI output of my computer, also working!
Second: The SPDIF output worked fine on a Windows 7 installation with PCM and DTS. I stopped using Windows privately.
Most success I got with debugging the SPDIF TOSLINK is: - With the HDA Intel sound cards Jack Retasking tool: - Check Showing unconnected pins. Actually, the TOSLINK is connected but shows "not connected" in the tool. - Manually override Pin ID 0x1e - Select "SPDIF Out" and "Apply Now"
- Then with PulseAudio Volume Control: - In the Configuration Tab, select "Profile: Digital Stereo (IEC958) Output" - In the Output Devices "Digital Output (S/PDIF)" appears and is the only option and in the advanced tab PCM, DTS, AC3, MPEG, EAC3, AAC are selected
- I check if in alsamixer tool that the SPDIF channel is unmuted
When I play a sound, the vumeter of PulseAudio Volume Control does react, see png attachment (https://postimg.org/image/5tu4rax9t/), but my external DTS receiver doesn't get input!
I really got stuck here!
Best, Marijn

You're sure that this pin is correct? I mean, did you get *any* signal from the SPDIF I/O by enabling this pin?
- Then with PulseAudio Volume Control:
- In the Configuration Tab, select "Profile: Digital Stereo
(IEC958) Output" - In the Output Devices "Digital Output (S/PDIF)" appears and is the only option and in the advanced tab PCM, DTS, AC3, MPEG, EAC3, AAC are selected

First off, you should try the normal audio PCM stream instead of DTS or such. It's possible that the SPDIF status bits aren't properly set and the receiver doesn't accept the non-audio signals.
And, as a primary testing, please test with aplay. You can pass -Dspdif or -Dspdif:1 option to transmit over the SPDIF device.
Last but not least, check the IEC958 status bits of the assigned PCM. You can use iecset program in alsa-utils for checking / setting the bits.

No signal at all from the SPDIF Toslink port! The reason trying this pin is that when overridden, it shows "SPDIF Out".

Ok, I deselected all other streams except PCM, no signal.. (Will do this in future tests).
And, as a primary testing, please test with aplay. You can pass -Dspdif or -Dspdif:1 option to transmit over the SPDIF device.
I was able to run "aplay -Dspdif" without errors. I also checked in another terminal if the alsamixer showed the s/pdif channels unmuted. They are unmuted, but I didn't get a signal to my audio receiver.
"aplay -Dspdif:1" didn't work: "Cannot find card".
Last but not least, check the IEC958 status bits of the assigned PCM. You can use iecset program in alsa-utils for checking / setting the bits.
iecset -x shows:
AES0=0x05,AES1=0x82,AES2=0x00,AES3=0x00

No signal at all from the SPDIF Toslink port! The reason trying this pin is that when overridden, it shows "SPDIF Out".
If so, the pin can be simply wrong. Usually when a PCM stream starts and "IEC958 Playback Switch" is on, the signal comes up.
You need to figure out which pin is connected to SPDIF. (And note that it's not necessarily the Realtek codec that is connected to SPDIF, although it's very likely.)
Or, there can be some vendor-specific verb, GPIO, vref or whatever non-standard control for enabling the SPDIF in addition.
Both above can be figured out only by the h/w owner -- or maybe better to ask the hardware vendor about it.
