I’ve been using the vero v for a while through an avr without issues using audio passthrough. I’ve now got it running through a hdfury arcana to get an earc output to a minidsp flex htx with the vero not using passthrough but decoding the audio to lpcm. The 5.1 channels are ordered FL FR C Sub SL SR but the vero v swaps the center and sub/lfe channels, how can I resolve this? Can the channel ordering be re-mapped?
Other devices seem ok, using mpv player from my laptop also has the channels mapped correctly.
Let me get this straight. Are you saying the minidsp expects the channels in the order FL FR FC LFE SL SR and not in the CEA standard (for HDMI) order FL FR LFE FC SL SR? That would be odd.
Probably - by massaging the ALSA config. I would have to go on an ALSA refresher course to advise - or are you familiar with ALSA?
The minidsp doesn’t ‘expect’ any particular order for its inputs, I configured them to the SMPTE standard that works with my other devices without issue, a layout which also works from my desktop and linux laptops.
Sorry if I’m being slow here. You are using a HDMI input to the minidsp. HDMI LPCM channels are in CEA order, not SMPTE order. What am I missing?
.. and why are you choosing SMPTE order? The default in your DSP seems to be CEA?
I can see that. I was not obvious to me, using multiple search engines looking for standard hdmi lpcm not once came back with that order, the 2 orders most listed where fl fr c s sl sr and fl fr sl sr c s, the hdmi wiki goes in to great depth on the physical connection, video formats and number of audio channels but I did not find any hdmi write up that explained the channel ordering standards. the Dolby support site and many others reference the smpte standard but no mention of cea.
If you want to dig deeper, search for CEA861. But I’m curious if your other devices do it differently. Same HDMI earc input?
Same input and tested also with usb audio input. I will reconfigure the input channels on the dsp and test out the other devices and see how they behave.
I think that would be my choice FWIW. No need for the Arcana.
It’s needed as I have other devices to connect, hdmi switcher to arcana to get the earc audio to the dsp, the display does not have earc output. The avr only has analogue audio pre-outs and I find the sound is better passing digital audio data directly to the dsp rather than an unnecessary DA conversion from the avr then AD in the dsp and another DA for output to the amps. Of course removing the avr means the source must decode the bitstream and output lpcm.
