no sound with allo boss

Hi there,
I bought an Allo Boss recently and downloaded the newest version of Volumio (2.348) today (after there was no sound with my older version), but there still is no sound, although the Allo Boss was detected by volumio. After clicking “play” there is a note: " Failed to open ALSA device “hw1:0”: No such file or directory. The “aplay -l” command receives thies information:
**** List of PLAYBACK Hardware Devices ****
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]

What did i do wrong?
Thank you for helping me.
Have a nice holiday,
Kind regards

Hi Balbuze,
thanks for helping me again! I am sorry, i forgot to write in the first post, that i already did that. And I tried several times, switching it to HDMI and back to I2S DAC or to Audio Jack, but it did not work.
Greetings

Good morning Balbuze,
I´ve solved the problem, well not really me, but now it works. I reconnected my USB-DAC to be able to listen to some music this morning and then, after switching back to the ALLO-DAC, there was sound through the ALLO and now it is also listed in the hardware, using aplay -l:
card 1: BossDAC [BossDAC], device 0: Boss DAC HiFi [Master] pcm512x-hifi-0 []
Subdevices: 0/1
Subdevice #0: subdevice #0
card 5: UA1G [UA-1G], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0

So thank you again for your advice and have a nice end of the year and a good new year!
All the best
Benni
