DAB-Z supports intents for play and pause buttons, so if your HU supports play/pause buttons (either from steering wheel, or it has its own buttons for it), the it will work. I use it sometimes from the launcher i use (Car Launcher - it can control active media player and send those intents).

Most HUs have settings for this - my Joying FYT unit on SoFIA has settings for decreasing volume or even completely muting it while reverse gear is on. Check it, maybe your HU also has it.

---------- Post added at 12:01 ---------- Previous post was at 11:51 ----------

I have disabled timeshift, and tested yesterday and today (~30 minutes). Result - no crashes at all. So the problem definitely lays in timeshift processing.

BTW, have you considered to try to get compressed audio stream from OMRI layer (after implementing raw stream recording), to use it with timeshift and recording functions, instead of recompressing it?
[Android Head-Units] typos1:
Just press the mute button, no extra development required.

Hey, after a while with another DAB adapter I'm back on DAB-Z.

I have changed the adapter into a new USB-version and using DAB-Z again.
[Android Head-Units] typos1:
I thought you said the reception was better on the other one ?
[Android Head-Units] iMattmax:
Yes, on the other device the reception is more stable (same antenna), but DAB-Z is the reason why.

The chinese app is crap, evertime it starts you have to choice a radiostation. The app didn''t recognize the last station.

This error is making me crazy. I have it since at least last four versions. It occurs 2 times on 3 both at cold or hot boot.

Any idea?

[Android Head-Units] realzoulou:
It shows that DAB-Z had crashed in the previous run. Since you did not mention that it crashes, DAB-Z seems to crash while the screen is already off.

Please send me a logcat (app only is ok). I am preparing a stability-only oriented release currently. I could address it then.
[Android Head-Units] royalhawk2002:
Ok I will do it today...do you need it when it crash or also when is running fine? Another question, since the app crash when the screen is off, you are right, if I enable logcat in the app it will remain active every time the unit boot?

Inviato dal mio SM-N960F utilizzando Tapatalk
[Android Head-Units] realzoulou:
Crashes are kept in Android's logcat buffer for several hours (sometimes days). Android's logcat is always enabled. With the button press in Settings->Info, my app does not change anything. It simply stores the current Android logcat ring buffer to a file. If you want to be sure that the crash is in the logcat you send me, then capture it, after you see the dialog next time.

Thanks, but i have no Mute Button, and i see not realy easy Way to exit DAB-Z.

I Have a Button for switching to the Launcher, but i user this DAB-Z runs still.
[Android Head-Units] NogenLunde:
You exit DAB-Z by pressing the back button on your unit (or such button in your car system).

DAB-Z also has an option for pausing when another app is playing.
[Android Head-Units] NogenLunde:
[MENTION=7838245]realzoulou[/MENTION] Are you aware that this is still an issue? Is there anything we can do to help?
[Android Head-Units] royalhawk2002:
[MENTION=7838245]realzoulou[/MENTION]

It seems I have a problem in non OMRI mode with my unit. 7 times on 10, when the unit exit from sleep or fron cold boot, the app try to connect to usb without success. (It try 5 times and then stop).

Regarding this issue, I need to confirm it making some more try in OMRI mode to see if happen also here.

I have a little issue also in OMRI mode. Sometimes happen that at start, both from sleep and from cold boot, I see full signal strength but audio is not reproduced. Selecting another station it starts.

[Android Head-Units] realzoulou:
Actually no. Since 1.7.81 there are no complaints anymore (ok, except you ;) )
[Android Head-Units] realzoulou:
On issue #1 (5x USB retry) I guess the root cause is in your unit and does not depend on OMRI or non-OMRI. Could be that the launcher starts DAB-Z before Android has detected the USB devices.

On issue #2 (no audio after wakeup, but change to other station fixes it): Yes I see this myself from time to time. Still investigating...
[Android Head-Units] realzoulou:
[MENTION=9350973]All[/MENTION]: If you find that OMRI mode does not show stations from a certain ensemble frequency (6D, 8D, etc.) although they appear fine in non-OMRI, please provide me with a OMRI verbose log.

Because Android keeps only 256000 bytes log buffer in RAM, please first go to your device settings->developer mode->logger buffer sizes and increase it to 4M. Reboot and then perform these steps.

Enable DAB-Z developer mode, enable OMRI verbose logging, restart app and then run a scan. After scan is complete, go to settings-info and capture the logcat (app only).
[Android Head-Units] royalhawk2002:
Issue 1 occured one time today also in OMRI mode. I read somewhere that some xtrons unots has problems with usb related to temperature but, if I am not wrong, it should occurs only with low external temperature. During di period we have more than 25°C here. In order to be sure that is not an hardware issue, I installed also the oen crap app. If will occur again, I will start the oem app and see if it is the same.

I thought it might be an error in my installation then, so today I tried this:

- Cleared cache and data: No change.

- Uninstalled, reinstalled latest: No change.

- Uninstalled, reinstalled different previous versions: 1.7.75 is the latest good version (76 is not available for download).

From 1.7.77 and up to the latest 1.8.88, the audio distortion/stuttering when changing stations is so bad, that all fixes and enhancements after 1.7.75 does not count up for it, so I will just keep 1.7.75 until more people report this bug.

Android 9, Snapdragon 625, 4 GB RAM.
[Android Head-Units] SkyBeam2048:
I am on Android 9 (HAL9k 4) with PX5 2/32GB and confirm some small stuttering when changing channels. I would not call it distortion but it rather sounds like the buffer isn't filled quickly enough and causing short "drops" and it only lasts for the first 3-5 seconds and then stabilizes. The same also happens if other foreground applications take resources (occasionally it happens for example during play store updates when DAB+ is running in background).

I tried to play with disabling/enabling audio recording, timeshift and suppress audio distortion settings. Actually the suppress of audio distortion I keep disabled all the time and the timeshift features I disabled as well due to recent info here that there was a bug hogging CPU). In general when I develop or run software it should run with as few CPU cycles used as absolutely required allowing low power consumption, better temperatures and overall more free resources for other tasks.

I was also thinking that a reduced CPU load could in worst cases trigger power management causing the CPU to change clock rates and causing side effects. Once I experienced that a certain device was causing constant power-state changes due to specific workload causing the CPU to be "halted" during power state changes for a short amount of times. So changing the application behavior did help here. But I think it's not the case here as of my analysis the stuttering happens even if the CPU is staying in the same power state during channel switch.

So yes, I can confirm some small distortion on channel switch on PX5 as well, but it's not nearly as bad as your post indicates (at least not to me). So your device either behaves much different (yes, snapdragon platform is of course different to the PX5 rockschip) or you seem to be much more sensitive. Perhaps you can provide a recording of how the distortion sounds on your device.

I am on 1.8.88 on my bench device btw.
[Android Head-Units] realzoulou:
[MENTION=10451415]NogenLunde[/MENTION] and [MENTION=3556393]SkyBeam2048[/MENTION] For a quick test, could you disable in DAB-Z settings->layout->show logos in station list ? Do it change anything?
[Android Head-Units] SkyBeam2048:
[MENTION=7838245]realzoulou[/MENTION] Unfortunately it doesn't change the behavior for me. When changing stations I it sounds like the sound stream has 2, 3, 4 small "hiccups" and none of the options change any behavior. I also tried disabling broadcast of media info in Android in the settings screen as well as disabling slideshow and any other option regarding layout. My default layout is with swapped station list (station list on the left (driver side), auto-hide station list, display logos and display slideshows.

After a couple of seconds listening to the station the hiccups stop and everything works just fluently. So for me it's not a big issue. To be honest I do not remember of version 1.7.x did not suffer from this issue or not and I don't mind too much. To be honest I am usually listening to the very same station anyway while driving.
[Android Head-Units] NogenLunde:
No change, unfortunately. I went further and disabled all logos and such, and even tried different "Android audio channel", since that option was introduced in 1.7.77. Nothing helped. The stuttering is not so bad that one can't live with it, but when I reverted back to 1.7.75 and experienced the smooth transition when switching stations, ...
[Android Head-Units] royalhawk2002:
Still on Issue#1, since yesterday the DAB adapter is not detected anymore by the HU. It was correctly working in OMRI mode before I switched off the car. After few minutes, I started again but no more connection to the adapter is performed. The adapter is connected to the rear HU OTG USB port. All the other USB are working, thus it could be the adapter or a bad connection. I will open a specific thread.
[Android Head-Units] IG_Vasilich:
[MENTION=7838245]realzoulou[/MENTION]

tested .88 several days. Result:

* without timeshift - no crashes.

* with timeshift - same crashes after wakeup of HU and changing ensemble (encoder?). See crash logs in attach.

P.S. Maybe it makes sense to expose stream from OMRI (if possible) and use it for recording and timeshifting, to avoid reencoding?

[Android Head-Units] royalhawk2002:

[Android Head-Units] rigattoni:
If the receiver does not locate the radio stations, you should think about your antenna configuration. There is nothing you can get working with just adding stations manually... They are out of your receiving range.

I hope you are not using a window antenna. In this case you should think about changing to a good roof antenna on your car. Nothing else is needed.

Isn't a good roof antenna, a good roof antenna without the information about the car (brand, model, year etc.)?

i have recently bought this one https://www.amazon.de/gp/product/B073R8KW7F/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 and installed it instead of windscreen stick-on antenna (delivered with USB DAB adapter). I can just agree with others - you should use roof antenna! I have now no audio skips at all! Before I had audio skips even in the city (Mayence in my case), but with new antenna i have no skips in any area of Bingen (>30km) and Darmstadt (> 50km), where with windscreen antenna it was no signal at all, even with new scan). Plus - i got DAB ensembles from other areas (Bayern and Oberfranken), that lay >100km from my location.

The original is not good enough if you experience dropouts with the one you have now. I ended up with the Funke adsc710 window antenna, that is giving me a stable signal in western Norway... also put the dongle in aluminum foil, it helps protecting from interference.

I'm not sure how big effect it has, in my case I did it when wifi dongle seemed to interfere, made improvements. But it wasn't really good before I moved the dongle away from the dab-stick... maybe moving the dab-dongle as far back in the car as possible will help you? (using longer antenna and USB cable)
[Android Head-Units] pwood999:
Agree totally. I did three things, which in combination have improved both DAB & FM Radio.

Moved DAB dongle to left side of car, with better antenna in rear window. Biggest improvement was better antenna.

Moved 3G dongle to above RHS instrument cluster (UK vehicle), so better 3G signal.

Fixed bad connections to car FM antennas (there are two in my car rear quarter windows).

[Android Head-Units] hans.vinkers:
I have put it as far to the front door as possible. The antenna is on the front window, next to the rain and light sensor (seat Leon 1p has wipers who are on the a pillar in pause) I found that the xenon ballast which are close to the head light, do interfere. I haven't really found out of that is over now.

I am really considering buying a roof antenna replacement. But I need fakra? Connector like original. I haven't opened the roof liner yet to see what connectors are there

Verstuurd vanaf mijn Z2 Pro met Tapatalk
[Android Head-Units] syk02jcb@hotmail.com:
A good roof antenna is probably the best option, but a decent window antenna is also good. I have it on a rear side window with good quality (of course a non-opening window). Anyway I will guess it's smart to get the dab-stick far away from your interference from xenon ballast and other interference around windshield.

If you go for a active roof antenna, check that it's ok with the low phantom power the stick gives (~4.7 volt), someone's need 5-12 volt. Then you might need an extra phantom adapter, like the Connects2 CT27AA158

Regarding fakra, I'm not familiar with your car, but fakra normally has a smb plug inside, so it's no problem to connect smb directly to fakra without adapter (it can be a bit tight, you may need to use some force to connect). I used this one for fixing my SMA to fakra: http://m.ebay.com/itm/Fakra-SMB-A-9...3D320978358338&_trksid=p2056116.c100408.m2460

I found a little bug [MENTION=7838245]realzoulou[/MENTION] when you have selected favourites and drive out of your region and need to rescan all favourites are gone. Allso gone when you come back in your first region and do a new scan

Verstuurd vanaf mijn Z2 Pro met Tapatalk
[Android Head-Units] syk02jcb@hotmail.com:
I think this isn't really a bug. In Norway some broadcasters use regional blocks, others the same nationwide. I live in a region overlap area, if i do a scan on a open area I will get both regions, but the channel list will be about 80 channels. I'm not quite sure, but the function called "service following" might help with this (uncertain if this is a part of the coming master piece) :)
[Android Head-Units] realzoulou:
This is not really a bug, it is intended to work like this.

Reason: The favorite flag is stored in the database "dab.db", which is the full list of stations after a scan. When a new scan is trigger, first the whole database is cleared and therefore also the info if a station was marked as favorite or not.

I am planning to allow for an (optional) incremental scan soon. Since this will fill up the station list with unneeded stations, I have already implemented a delete option for stations in the list.

Regarding service linking/following: I gave a test version to a user in Norway to try it out. I am very unsure if it will work. He has not replied yet.

In Germany it did not work at all. The Witson version however also works in Germany, so it looks like in the Witson version they have changed/optimized the service linking source code.
[Android Head-Units] syk02jcb@hotmail.com:
I live in an area in Norway where it is good to test the service following, it's mulitiple senders around from two region blocks (have tested tiny audio adapters on a certain road for this). So if you don't get a answer from other user I will be more than happy for testing it rather quickly :)

Does this app allow to be controlled from other apps? I have built a media controller app for the PX5 HU, and also bought a DAB stick. However this app doesn't seem to share any information, or respond on media buttons.

Is there anything that can be done about the looks of this app? It looks horrible (not really your problem ofcourse). Would be nice to have something more like the FM app.

There also seems to be a big delay between switching apps. Is this something that can be fixed?

Would be easy to control the app via my app. Would also give it Android Auto support. ;) https://xdaforums.com/android-auto/...-development/app-fm-radio-controller-t3625038

https://www.rgsound.it/7562030-kit-splitter-attivo-universale-am-fm-dab_calearo-id-43344.html

So i can use my original roof antenna.

Then, I don't understand a thing. But if the cluster.conf file does not contain all the frequencies of my country, how does the radio scan the radio channels not present in that file? Does it not work as in the satellite decoder where the scan relating to the frequencies entered in the satellite.xml file is performed?
[Android Head-Units] rigattoni:
You can try this splitter, yes.

The DAB app scans all available MUXes and provides all at your position available stations. That has nothing to do with any settings in the app. Just do a complete scan and you will see it works..
[Android Head-Units] IG_Vasilich:
it won't work if your antenna is active (i.e. has power cable attached), because active FM/AM antennas have filter for FM and AM ranges, so DAB frequencies will be filtered. So check first whether your antenna has power cable attached.
