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
