This task has low priority …
Hi… unfortunately i continue to have issues with USB audio …
… Last (casual) success doesn’t happen anymore… with any card i use… (all class compliants, of course)… You really have USB Audio working right after webconf selection ?..
Are your Hifiberry connected to the system while plugging the USB device?
Do you refer to webconf menu? If that, Yes, that selection points on USB device. But last time It worked the opposite way (hifiberry selected, USB inserted)… which makes no sense, in theory… Or you are referring to another way to connect which i don’t know…
No no … i say phisically connected, but i see yes, it’s connected.
Anyway, it shouldn’t be a problem. Please, send the “lsmod” output and the “/boot/config.txt” content again.
Regards,
ok,this is situation with usb audio inserted.

in this state, only hifiberry works
Just in case i give you the actual list of cards typing cat…
/etc$ cat /proc/asound/cards
0 [sndrpihifiberry]: HifiberryDacp - snd_rpi_hifiberry_dacplus
snd_rpi_hifiberry_dacplus
1 [Device ]: USB-Audio - USB Sound Device
USB Sound Device at usb-3f980000.usb-1.3, full speedIt’s strange. Please, reboot from command line and send again everything.
Have you modify your /etc/modules.conf file?
I’ve noticed that your USB device is working at “Full Speed”. The RPi3 has some issues with USB interface in that mode. The next option in ‘/boot/cmdline.txt’ helps to solve these issues partially:
dwc_otg.speed=1
After rebooting you will have your full speed devices working, but you’ll loose support of high speed devices.

Actually i didn’t. In the meantime i wanted to try with two usb cards and a keyboard controller plugged simultaneously…and finally one of cards randomly was taken as first, but system becomes unstable, hangs, and After reboot It gives error (no default snapshot loaded, etc) … Anyway i always rebooted from command line…
my USB cards are all hi Speed (usb2)… i added the option but nothing changed. In some cases peripherals remained unrecognized…
Have you tried to modify the jack options? You could try to put “-dhw: Device” and not 0, 'cause probably 0 is the sndrpihifiberry device and not the USB.
you can’t imagine how many trials i made on jack options too, before re-posting the issue again 
HW position numbers change randomly… expecially if i add a usb midi controller… it appears together with usb audio devices, and makes further changes again.
Consider that it’s so anarchic last time usb audio worked with webconf selection put on hifiberry 
totally non sense…
But switching card type thru webconf should avoid this manipulation. i think is exactly for automatically load the usb device as HW:0… and ignoring others. or not?
today i checked. having never touched it, don’t know if should be populated or not. mine is totally empty
uuh… maybe is the one inside /etc/modules-load.d? ok there is something 
anyway never touched it .
I know that the position’s number change every time, but you can put the device name instead of the device’s number. I’ve written “-dhw: Device” 'cause is the name of your USB device (you can try aplay -l to see the device name, but it’s the same of /proc/asound/cards).
Have you tried insert the name in -dHw parameter?

uh, it seems it works… but i’m still checking with different interfaces… anyway thanks
