AMP2 Settings with Volumio

Bought the AMP2 kit.   Pretty worried when sparks came out of the power socket when plugging it in but HiFiBerry support said it was normal given the strength of the capacitors.   :-|

 

Was having problems getting sound out of the Volumio 2.   

The green LEDs on the AMP2 board don't light-up, which is a give-away even though you can logon to Volumio and manage the raspberry pi

Did a factory reset.  Several times but still no joy.

So used the following settings in playback settings and rebooted... and it all worked.  Ta Dah!   Why don't they tell you this?

  Hi, i am facing the same problem. But there is no cure. With the above settings i only have the choice to choose a 'Software' Mixer (which is i think what i want). And i have no sound. Newest volumio version (April 2019); Hifiberry Amp2 and Raspberry Pie 3B+.

   

  Any help? Any suggestions?

  I have no green LED flashin on the Amp, there is no documentation about that, where is the LED?

  Any help would be greatly appreciated.

  Dear Daniel, i do not understand the question, what do you mean with driver? Where to select? hannes

  You need to configure the board in the settings first. What did you configure there?

  Best regards,

  Daniel, i just did a factory reset. The first question volumio asks is a name for the machine and then it asks if i use I2S. There i select the Hifiberry DAC plus... I do not know where to select a board or a driver. It is not in 'System' and not in 'Playback'... where can i find it?

  Hi,

  I'm not a Volumio expert. Please login via SSH and post the output of the command

  aplay -l

  Hi, did you save the settings, as shown in the images at the start of this topic? And then reboot the system?

  it works! i did not change a thing. although it was not the first reboot (@EricV)... i have no clue what it was..

  still one question: what exactly is a hardware mixer? does it mean the amp plays full power and i have to deal with the signal (eg volume) with hardware? or what is the differemce between soft- and hardware mixture.. sorry i am not a nerd...

  maybe i should reboot and look if it still works...

   

  THANK YOU for all the support!

  thanx eric. after rebooting (anf turning the machine off) i get nothing... not even an ip address (wireless). i don't get it. i had similar problems with another raspberry and it turned out that the microsd card was a bad one.. maybe i should change it.. i do not really know what my problem is.

  anyway i will read the mixer article...

  Is it possible to connect the pi with a network cable?

  Hannes May 22, 2019 07:24

  eric, yes i can do that. i can see the device in the router software with an ip4 address (not an ip6), but i cannot get a connection, wifi doesn't work at all allthough it worked before...

  Hi Hannes, I think this has to do with your volumio installation, we shift to a "Volumio" discussion, more then HifiBerry. This might be the wrong place for that.

  When your wired connection works: did you try 'volumio.local' in your webbrowser? And if that doesn't work "http://ip_adress_of_your_pi"?

  That should get you to the webinterface, where you can check network settings, including the wifi setting (network name and password)

  i didn't know we are in BeoCreate area.. i thought this is the amp place... i tried everything in the browser. i tried putty. i do not know why it sometimes works and sometimes not... even with a wrong DAC and Amp installation the user interface should work or at least some kind of connection (excluding http). i will try a few more things and then give it back to the vendor in order to give me new components.. i suppose it is not a software problem..

  The ‘beocreate’ thing was my mistake. But i have corrected that.😀

  The issues you describe are exactly the reason why i think that this is caused by your volumio installation. By default ssh is not enabled in the volumio image, so putty will not work. 

  I would recommend to do a fresh volumio installation. Before you return the hardware.

  Dear Eric, thank you for your support (and patience :-).. today it worked again (wireless)... while online i changed to hardware mixer (type 'digital') and it works as good as 'software'.. i enabled ssh by adressing http://volumio/dev which is fairly easy. does it make sense to give an dmesg output? there are some alerts.. but i am no expert...

  I think it will be more helpful to discuss the dmesg output in the Volumio forum, on the Volumio website. You will find the experts there.

  regards

  Dear Eric, i just installed voumio the second time. all worked perfect this time (since i know the parameters now...) and i had sound from the beginning and the green led flashing on the amp. the dmesg file looks different and way cleaner... i just have a little firmware problem with the wlan chip which the system solves by ignoring it i suppose... i booted and rebooted several times, pluggin the power source in and out and so on. wifi works, all is perfect!

  i use an intenso microsd card. with this card i had problems in the past, but i always mix up transcend and intenso. i never had problems with a transcend card. so all is good now. when i will face problems i will change the sd card and reinstall (it takes 10 minutes). i guess the card and installation was the problem, but who knows?

  THANK YOU

  ps: with all this i build an internet radio using very good Tang Band broadband speakers. i enjoy it!

  Hi Hannes,

  That’s good news. One last ‘warning’, if I may: I always power down the unit by using the system shutdown menu option of Volumio. Never just pull the power plug, this will very likely damage your sd card.

  Enjoy!

  Regards,

  Eric

  Yes i do exact the same ( i wrote it wrongly). To restart the pi you always have to plug out and then in again that is what i meant. i never plug out without shutting down first (i know this can cause a lot of problems)

  ;-)

  Best regards and many thanks
