Added all cards till the previous post.

I had a quick look, a few remarks:

Not all the DACs in the json list have a corresponding entry on the source files from the kernel tree
I don’t understand how to link the declaration from the source file to the cardname we need. As an example, I had a look to the FiPi DAC, the name I get from aplay -l is “Audio”, in fe-pi-audio.c the declared name is “Fe-Pi Audio”. If the cardname has no spaces, the matching is correct.

ashthespy · February 12, 2021, 10:24pm

Yep, the these are just the ones that need drivers. For the ones that can get by using the audio-graph-card or simple-audio-card will have their name under the label key in their corresponding overlay file… Example allo-boss2-dac-audio-overlay

Interesting, looks a bit odd that it is returning only the part after the space? From a quick peek, aplay should be calling snd_ctl_card_info_get_id and snd_ctl_card_info_get_name from alsalib, and I doubt it’s doing something funky there.
Does this happen only on Volumio? Or even on Raspbian?

What part of the aplay output are you actually interested in?

card 0: Audio [Fe-Pi Audio], device 0: Fe-Pi HiFi sgtl5000-0 [Fe-Pi HiFi sgtl5000-0]

According to ALSA terminology, this would be

card = 0;
card_id = "Audio";
card_name = "Fe-Pi Audio";
device = 0;
device_id = "Fe-Pi HiFi sgtl5000-0";
device_name = "Fe-Pi HiFi sgtl5000-0";

The terminology here is a bit confusing (for me), so I was under the impression you wanted the card name, but it looks like you are interested in the card_id?

Looking at the dacs.json entry, this is mapped as:

{
"id":"fe-pi-audio",       
"name":"Fe-Pi Audio",     // ALSA card_name
"overlay":"fe-pi-audio",
"alsanum":"2",            // ALSA_card
"alsacard":"Audio",       // ALSA card_id
"mixer":"PCM",
"modules":"",
"script":"",
"needsreboot":"yes"
},

according to the indication Tim gave me, it is the part right after the card number, before the square brackets (highlighted in bold)

card 0: Audio [Fe-Pi Audio]

Hi,

I did extensive testing with the TerraBerry DACs (version 2 and version 3).
Independant on the Volumio version it shows up the aplay -l command output is different on TerraBerry2 and TerraBerry3 (see below).

@Michelangelo: It seems there is a bug in the newer Volumio versions that leads to these DACs are not working with volume control “none”. The only workaround is to choose “software” mixer and set the volume to 100%.

In the mean time i had a look at the UNSUPPORTED Aoide DAC II.
For those who got it managed to successfully install the drivers from:

@Darmus:

TerraBerry2 DAC - config.txt:
(same at TerraBerry3 after setup SD card from scratch…)

-------------------------initramfs volumio.initrd
gpu_mem=32
max_usb_current=1
dtparam=audio=on
audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1

include userconfig.txt

Volumio i2s setting below: do not alter

dtoverlay=i-sabre-q2m

RemotePi lirc setting below: do not alter

TerraBerry3 DAC -

I had to reflash the SD card because i used it for another installation.
And now (fresh install - i get the same output as on TerraBerry2)
I didn’t edit any file manually on none of these installations

config.txt:

initramfs volumio.initrd
gpu_mem=32
max_usb_current=1
dtparam=audio=on
audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1

include userconfig.txt

Volumio i2s setting below: do not alter

dtoverlay=i-sabre-q2m

I don’t know what is going on there.
Interestingly. The hardware mixer has been activated and there is sound at the output. I am able to operate the volume controls in the UI - but as expectable the volume is not changed and is always at 100%

Same after a restart. When selecting the volume mixer there is only “none” and software". Once selected “none” the “hardware” setting that has been choosen as default is gone (how it should be…)

I hope in Version 3 of Volumio the TerraBerry2/3 and Allo Piano 2.1 will get back working as expected…
