Hello realzoulou

I was reading your forum and came across a similar issue I am having with a few DAB+ stations in OMRI mode where I have no audio.

I am in Melbourne, Australia and there are 6 stations that has no audio out of 70 stations. I am using DAB-Z Version 1.8.91

The list of radio stations where it comes up with a message saying, “No audio, will retry” are as follows;

3AW Service ID 10CA Ensemble ID DAB Melbourne 2 (F004)

Magic1278 Service ID10CB Ensemble ID DAB Melbourne 2 (F004)

News Talk Sport Service ID 10CC Ensemble ID DAB Melbourne 2 (F004)

RSN Carnival 1 Service ID 10C1 Ensemble ID DAB Melbourne 1 (F003)

RSN Carnival 2 Service ID 10C3 Ensemble ID DAB Melbourne 1 (F003)

TAB Live Service ID 10C2 Ensemble ID DAB Melbourne 1 (F003)

I did send you an email on the 12th August with the raw data, but never heard anything back.
[Android Head-Units] realzoulou:
No, I didn't. I find DAB-Z on pictures of head units every now and then, too. It's on Play Store. No one needs to ask if he can install it...
[Android Head-Units] realzoulou:
Thanks for the raw recordings. Sorry for not replying. I had a look at them and see the root cause why no audio comes. However, don't know yet what to change in OMRI source code.
[Android Head-Units] ethalthefrog:
No worries. Thanks for your prompt reply ???
[Android Head-Units] typos1:
Yeah, ok fair point.

Hello [MENTION=7838245]realzoulou[/MENTION] thanks for developing the app further :)

i want to "annoy" you again with some feature requests :D

Would it be possible to add some kind of demo mode to start the app altough no dongle is connected ?

This would it make easier to preconfigure the software when the unit is not installed to a car and to see if a background image does fit well :)

Second question i already asked some time ago, any idea if twintuner (two dab+ dongles) support would be possible some time in the future ?

Sincerely Kri

Installed on a Erisin PX5 with MCU S32F0 and Android 10 (fake) and it is perfectly working.

I can't remember how to enable the hidden menu in the app, someone could help?

Thanks

Hi,

I realy enjoyed your app on my android headunit but now i changed to a android tablet.

On the tablet is a external amplifier and the dab+ stick via a usb c hub connected.

Here comes the problem: when the external usb amp is connected the dab+ signal gets to 0 and there is no sound. When unplugged everything works fine.

Is there a simple solution how to use your app with an external amplifier?
[Android Head-Units] IG_Vasilich:
I assume that you have USB DAc connected to external audio amplifier, and not USB Amp. Correct?

Are both USB devices (DAB adapter and USB DAC) connected to same hub? if yes - have you tried to use active hub (that has external power supply)? Have you tried to make kind of shield for DAB adapter (with e.g. grounded copper foil) ?
[Android Head-Units] 0xt0mt0m:
Yes, sorry i meant a USB DAC instead of amplifier.

The USB hub was powerd externally. But what i have seen yesterday the signal gets better when the devices are not close to each other, so i think its a hardware thing and not software related.

Thanks anyway for your help.

AFAIR in the past (2 months back? and more) after switching off ACC in my car, the display went dark after 1 second, and HU went sleep. After switching on ACC the firmware of HU restored last app in foreground, and if it was DAB-Z, then i continued to hear it.

Now after switching off ACC i see the message in DAB-Z that adapter was disconnected, and after that DAB-Z closes. All this happens very quick (1 second, before screen gets dark), but after switching on ACC the HU restores launcher as it was the last app before HU went sleep last time.

Have you changed some timings in DAB-Z in last version, that DAB-Z recognizes adapter disconnect much quicker than before?
[Android Head-Units] realzoulou:
No, there was no change in the app that could explain what you described. DAB-Z always exits asap when it detects that the USB adapter was removed. No delay.

[Android Head-Units] stesofeu:
Well, don't know what a VW's head unit looks like cause I drive a Nissan X-Trail and a Ssangyong XLV both with Android head units. But if its possible to manage several designs in DAB-Z it would be perfect!

Hi, I'm using last version but I have this question: in italy we have 3 "frequences" and I can't choose these from the app, then I can't listen not all radios present in Italy.

I'm using OMRI, may I have to try to search without this feature?
[Android Head-Units] IG_Vasilich:
acc. to https://www.worlddab.org/countries/italy#regulation_and_spectrum in Italy there is only Band III in use. So what "3 frequences" are you talking about?

service following for OMRI mode

Hello.

I'm from Czech Republic. the DAB CRo transmission is here divided into channels 12C and 12D. Will the following service function be in OMRI mode? In not OMRI mode playback stutters.

Thank you for a perfect and functional application.:good:
[Android Head-Units] IG_Vasilich:
DAB-Z scans complete frequency range that is supported by DAB+ Adapter, and it does it automatically since beginning of its existence. You don't need to set frequency somewhere in DAB settings.

So if you cannot receive some stations - then you are probably not in receiving area for that station. Refer to https://www.worlddab.org/countries/italy#coverage to see what stations are available at your place.

Hi, I am based in the UK and I just switched to the DAB-z app from DAB+ that comes with the HAL9k Mod. Works really well except I can no longer receive Radio 5 live, switching back to the old DAB+ app and it works no issues with full reception. Is there any setting I may need to tweak to get this to work?
[Android Head-Units] okij:
You could switch from OMRI mode to legacy mode as a workaround, but then you don't have the benefits of OMRI mode (which you don't have in the DAB+ app either.)

Or maybe you can help the developer to fix this issue in OMRI mode by providing logs and/or raw recordings of Radio 5 live. [MENTION=7838245]realzoulou[/MENTION]: Could he help you with this?
[Android Head-Units] marcus82:

[MENTION=2930244]dampy78[/MENTION] : Is BBC 5 live never giving audio? The logs you provided only show that CRC error occurred when you switched to BBC 5 live. I would need the raw recording files following the instructions below:

Precondition: OMRI mode is enabled.

1. Enable Developer Menu: tap 7x on Settings->Info->Version: -> 1.x.xx, then close Settings, re-open settings

2. Enable OMRI raw recording (you don't need to activate verbose logging)

3. Close DAB-Z (raw recording enable/disable requires a restart of DAB-Z)

4. Reopen DAB-Z

5. Select BBC 5 live

wait for ~30 sec

6. Disable OMRI raw recording and restart DAB-Z again.

In DAB/rec folder several .raw files are now stored. Copy them to a USB stick using a file explorer app on you headunit and then provide them to me or attach them here

[Android Head-Units] dubist:
im using this APP on my XTRONS PX6 with Android 10, everytime when i go with gear in reverse the camera turn on and decreasing volume is not working, the Audio stops completely.

I have activated this decreasing volume function on the HeadUnit, with Spotify or Radio App its working without Problems, only on DAB-Z insted of decreasing volume it stops completely.

Why ?
[Android Head-Units] realzoulou:
Please provide me with a logcat (Settings-Info).

Create it after you put the reverse gear in and out.
[Android Head-Units] surfer63:
Hi, like also answered via PM, the 1.8.92 works for me as well. I live in the Zwolle area. All NPO stations via OMRI do work.

However, in the last 1.8.91 it also works for me on OMRI.
[Android Head-Units] dubist:
In attachment you have my logcat
[Android Head-Units] realzoulou:
[MENTION=4032446]dubist[/MENTION] It seems the DAB signal drops out while you have the reverse gear in :eek: Because the app cannot decode audio anymore, you hear silence. I think your unit produces some electromagnetic noise when showing the rear view camera.

Can you please try to place the DAB USB adapter as far away from the unit as you can ?
[Android Head-Units] dubist:
I must say that when i put my hand on the Touchdisplay or at the front of the radio the signal strength goes down without touching the Radio.

Do you know why ? Perhaps something is wrong with the USB DAB Adapter ?

Cause when I'm hearing with Spotify or Radio FM Sound is working without problems and without signal drops.
[Android Head-Units] realzoulou:
I can't tell you why. I can only give the advice to put the DAB adapter away from the unit.

I assume that not all stations show the same behavior. Typically such EMC noise has a relatively small bandwidth and so only stations from the same ensemble frequency should be impacted.

FM has a different frequency range than DAB, so you cannot fully compare them.

Spotify is an Internet music streaming app, which is a totally different technology than FM or DAB.
[Android Head-Units] dubist:
I made a test

When I activate the rear gear the signal strength goes down.

Than i tried via obd tester to activate only the rear reverse light without turning on reverse gear or rearcam.

When the rear lights goes on the signal drops down.

The lights are LEDs ? interference ?
[Android Head-Units] typos1:
Yes, been mentioned on here before, try wrapping the DAB box in ally foil.
[Android Head-Units] rigattoni:
Antenna in the car with windshield antenna?

You should use another antenna outside of the car.

Are those LED from OEM, or aftermarket something?

Those aftermarket LED are real spreader of interference.

3* yes they are Aftermarket

[Android Head-Units] realzoulou:
Hmm, I managed to get the first audio samples out from the raw recording, but I am still debugging. Main root cause is the use of the "old" DAB standard. OMRI was developed with the current DAB+ spec and the backwards compatibility is sometimes missing in the code.

That sounds like a 1970s mentality, not a 2005 one. Not sure when exactly you started to be able to do it online, but before that you could send it off (using the postal system that we invented in 1865 !), you didnt have to go to the tax office.

I installed my brand new Pumpkin AE0373B-01B PX5 in my VW Touran. I use the DAB 004 standard box with the enclosed dab glass adhesive antenna. I have the reciver under the flap at the top of the dashboard. The reception on channel 12C is very bad, no matter where I go. The other channels have full reception.

can this be due to the mounting position of the reciver ?

is the reciver defective?

which receiver do you use?

my receiver seems to be of poor quality.
[Android Head-Units] realzoulou:
If only 12C is affected, then there could be some interference with something in your car (e.g. the head unit itself). Try placing the USB DAB receiver away from the head unit as far as you can.
[Android Head-Units] x2optimizer:
ok I'll try it. if that doesn't help I'll get another USB DAB receiver.

does anyone have any experience with this one?

Hi.

Just a question.

What's the benefit of using OMRI ?

When I use OMRI I cannot see nor hear any diffrence at all.

That is, not here in The Netherlands
[Android Head-Units] giant53:
One benefit that I noticed is that switching channels within the same band is immediatly. In the Netherlands switching between NPO 1, 2, 3, and so forth is instant. In non-OMRI mode it takes several seconds before you can listen to the next station.
[Android Head-Units] IG_Vasilich:
Another advantages - support of all possible slideshow formats (broadcasting pictures), feature to detect/highlight/notify "artist - title" (broadcaster dependent), and timeshift feature (in case you have compatible hardware).

One disadvantage - Service following is not implemented in OMRI mode.
[Android Head-Units] realzoulou:
Not much longer ... I am currently implementing Service Following into OMRI.

I expect the result being superior compared to the legacy Service Following. Not sure though when I will be able to release this. May take another few weeks.

Update on the "No audio" issues with BBC Radio 5 Live and BBC Radio 5 LiveX Sports:

With the

Hello,

when i receive phone calls or make phone calls over bluetooth the dab-z app does not reduce volume of the dab music ?

Is there any solution for that ?

[Android Head-Units] realzoulou:
This is working fine usually. The issue is with your Android firmware from your supplier. Ask for a fix.
[Android Head-Units] Zabzd:
Hello.

if I save one station from the frequency 12D "CRo Dab Prague" to the "Favorite" after restarting the application, the station from the sequence 12C "CRo Dab Prague" will automatically be added to the "Favorite" in the first place and it will start even if it is much worse signal. You can fix this error.

Thank you

How other music players (any external app (like PowerAmp, AIMP, Neutron, Stellio or similar), not stock music player) are behave in this case?

If the volume is not reduced also for 3rd party players, then you have bad luck and your HU manufacturer hasn't implemented some standard behaviors for its custom Bluetooth solution.
[Android Head-Units] enzo80:
Yes other 3rd party apps also produce this problem.

This is a china android car hu.

The seller does not respond to my request.

The original installed apps such as radio and media player reduce volume...

Can i change bluetooth telephone app to solve this problem...
[Android Head-Units] realzoulou:
There are no alternative Bluetooth apps. Only the one that came with the unit will work. You need to accept this behavior, or buy a different head unit.
[Android Head-Units] enzo80:
Ok the seller send me latest firmware.

After i installed it, there is new behaviour of dab-z

When i receive or make phone calls the volume is reduced for 2 seconds, then dab-z plays in full volume while making phone calls ?????
[Android Head-Units] typos1:
This is nothing to do with DAB-Z or [MENTION=7838245]realzoulou[/MENTION], it is do do with your head unit, please look in the Android Auto section for threads about your unit and open one yourself if you cannot find any..
