[Solved] Audio cannot output to Wiim Ultra through HDMI arc port

[planykao]

Configuration
TV

• Sony Bravia 7
• audio configure to PCM
• enable HDMI CEC.

Wiim Home

• Auto-Sensing of HDMI and Optical enabled.

Issues

1. WiiM Ultra cannot turn on when TV is on.
2. WiiM Ultra cannot turn off when TV is off.
3. Even if WiiM Ultra is turned on by TV, WiiM Ultra cannot receive audio from TV. WiiM Ultra can display volume when adjusting volute via TV's remote control.

Those issues are not happened all the time. Any one has same issue?

Have you enabled CEC in the audio input settings in the device settings of the WiiM home app?

Yes, CEC is enabled in WiiM home app.

I also try to swith audio input in WiiM home app when there is no sound, but it won't help. I have to keep reboot TV and WiiM Ultra to solve this problem.

Same issue for me. Similar sony tv, same year. I've tried everything but reboot. I'll try when I'm home for work this evening

HDMI CEC has always been a bit of a black art in my experience. Sometimes solid, sometimes flaky.

It's been around long enough, you'd have thought that all the kinks would have been ironed out by now.

My Sony X90L is similar to your B7, it turns the Ultra on and off, or standby mode I guess.

Sony audio output set to Auto 2 and I get LPCM from stereo sources and DTS, and AC3 from DD source.

Sometimes no audio, I have to touch Vol Up on the Sony remote to get it.

Ultra Audio settings = Fixed Volume Output, I think that is for all inputs.

Sony audio output:

Audio system prioritization = on
Sound mode sync = on
AV Sync = on
eARC mode = off
Digital audio out = Auto 2
DD+ output = DD+
Pass through mode = Auto

The Sony mutes the Ultra rather than putting it into standby (a common issue with many devices). Have you set the Sony HDMI-CEC to power off devices when you switch off the Sony? That works with a Denon Home Amp.

DD+ output = DD+

Since the Ultra does not support DD+, this could just as well be set to DD.

as far as I know it's in standby mode when I turn off the TV, I will check settings. Still very new..

It seems to see everything, even DTS.. so far. I will try changing to DD with DD+ input. I think almost all streaming services are in DD+, so if I change to DD is this telling the Sony to process the audio as opposed to pass through to ultra?

Apparently, devices that support DD, but not DD+, can ‘extract’ DD from DD+ so that is why it will work either way. I doubt it will make much difference.
An aside, the reason that support for DD is now more widespread (eg. some of the new Nodes as well as the Wiim Ultra) is that the patents have expired for DD, but not yet for DD+.

Interesting!

I tried a quick test tonight and couldn't hear a difference. I guess no reason to set the TV back to PCM going forward. works okay, but my center channel lacking compared to past 3.0 systems of course.

TV audio is about the same as Pro using Optical and basic SMSL DAC..

Works well with Tidal connect - the main reason for the box. DAC is ok, will upgrade that soon.

Did you use the HDMI cable supplied with the Ultra to connect it to the ARC port of the TV?

I had similar problems with my Sony TV which went away when I used the HDMI cable supplied with the Ultra. Guess my HDMI cable was too old. the sound worked shortly also with my old cable but stopped during watching a show. I was not able to get back the sound.

Now, everything works as desired with the supplied cable.

Yes, Device auto power off and TV auto power on, but I didn't go through "External device setup" not sure if that will help. still have to touch the up volume on the Sony to get sound sometimes.

So far no DTS (Plex) with TV set to output DD on the latest firmware. will look it over again.

How do you like the Denon home amp? I would have to get passive speakers, but looks nice.

It seems to be good and together with a Denon CEOL N11 I have a multiroom solution that is more reliable than Chromecast, and I can use Qobuz if I plug my Wiim Pro in one of the Denons.

This issue is not happened after changing another HDMI cable, it's weird, original cable works well with DTM-7.

No, I didn't use the HDMI cable supplied with the Ultra, because it's too short. My old HDMI cable works well with Sony TV and DTM-7.

After changing another HDMI cable(not supplied with the Ultra), this issue seems gone.

Yes, the supplied cable is quite short. I just wanted to highlight that incompatible/old HDMI cables might be the culprit of some of the HDMI issues described on the forum.
