DAB-Tuner not Found

[hjfisch]

DAB Tuner seems to be found , but telling me Not Found

[rern]

Please try: sed -i 's/timeout 1/timeout 3/' /srv/http/bash/settings/features.sh

[hjfisch]

Still the same : No DAB device found , but now I cannot switch-on the device . Before I was not able to switch-off

but now I cannot switch-on the device . Before I was not able to switch-off

It looks like it crashes.
What version of RPI are you using? DAB player is useless for RPI version <=3 due to lack of CPU computation power. See another thread.

Raspberry Pi 4B Rev 1.5

Please, see if you can find any station using:
/bin/dab-scanner-rtlsdr -C 5A

[hjfisch]

No stations . I've tried two dab-sticks now with the same result.
One of them was running last year , but I do not know with which version of rAudio .
I

DAB reception is heavily rely on signal strength from antenna so strongly recommend to check this. I have several stations that are detected but unable to play.

[hjfisch]

I made a new sdcard with the latest build and I'am not able to switch DAB on and yes I've controlled my antenna which is still the same
I used before . The stick seems to be detected , but rAudio says : No DAB devices found . Maybe the plugin needs an update and some libraries are not compatible with the latest versions .

[kan-ibal]

Should /bin/dab-scanner-rtlsdr -C 5A works it means that is detected.

[hjfisch]

A little screenshot .
It detects a lot of stations . The screenshot shows only some .

[kan-ibal]

It looks good. So if I see that you have E4000 tuner and it is not working but it works for me with no E4000 tuner then you can try:
sed -i 's/rtl_test -t/rtl_test/' /srv/http/bash/settings/features.sh

[hjfisch]

Nothing has changed . I have a stick with no E4000 tuner too , but it is still the same.

[kan-ibal]

I can read Elonics E4000 tuner from screenshots.

[hjfisch]

Yes , but I have 2 different Sticks .
I've changed it now and this screenshot is from the one without E4000

[hjfisch]

I've testet now with a RPI 3B+ and still no DAB Device found

[kan-ibal]

OMG! Tinkering with rtl_test in /srv/http/bash/settings/features.sh I ended up with the same "No DAB devices found" but I can search for stations in Library/DAB and play it. It looks like PHP sees it as disable only.
Use your no E400 dongle, revert to rtl_test with -t and go Library/DAB to see if you can find stations.

[kan-ibal]

It looks like PHP sees it as disable only.
Not directly related but $id_data table from /srv/http/settings/features.php looks odd for upmpdcli
'upmpdcli' => [ 'label' => 'UPnP / DLNA', 'sub' => 'upmpdcli', 'setting' => false, 'status' => true, 'exist' => 'spotifyd' ]
there should be 'exist' => 'upmpdcli' instead of 'exist' => 'spotifyd'

[kan-ibal]

There is $( '#dabradio' ).toggleClass( 'disabled', ! S.dabdevice ) in /srv/http/assets/js/features.js but
dabdevice variable is missing in data of /srv/http/bash/settings/features-data.sh
e.g.
, "dabdevice" : '$( timeout 1 rtl_test -t &> /dev/null && echo true )'

[hjfisch]

Due to the fact that I cannot switch-on DAB , there is no DAB-Icon in Library . In /srv/http/data I can find a directory called dabradio

Now rAudio does not see my DAB-Sick anymore.

[hjfisch]

Got it working now with rAudio image rAudio 20231022 .
So it seems to be a bug in in latest rAudio version .
Tested both Sticks and both are working with this version .

[hjfisch]

Due to the fact that there are to many bugs in rAudio20231022 , I need a fix to get it work in the latest build .

[kan-ibal]

I have already provided the solution:
sed -i '/, "dabradio" : '$mediamtx'/a , "dabdevice" : '\''\$\( timeout 1 rtl_test -t &> /dev/null && echo true \)'\''' /srv/http/bash/settings/features-data.sh

[hjfisch]

Hello ,
I'm sorry , but your solution does not work for me . Still the same "No DAB Device found" .
Only with some old versions of rAudio from last year it is working .

[hjfisch]

Now DAB-plugin could not be installed .

A few minutes later it works .

DAB Icon is greyed out . Scanning Stations seems not to work .
