  1. thanks! the default now set to the USB DAC now, but i found Mopidy not play to it...... trying to figure out why .... by the way, can i define card number of the USB DAC? as it will become 1 when plugged before boot, and 2 when it is plugged after the bootup. thanks! Joseph
  2. hello, i am setting up Mopidy in Orange Pi PC2 with armbian. but i found it only playback to the on-board sound card not the USB DAC i connected. root@orangepipc2:/# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Codec [H3 Audio Codec], device 0: CDC PCM Codec-0 [] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: allwinnerhdmi [allwinner,hdmi], device 0: 1c22800.i2s-i2s-hifi i2s-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: Audio [iFi (by AMR) HD USB Audio], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 i found there is no asound.conf in /etc ... i tried alsactl store 2, but Mopidy still playback in 0 in /etc/modprobe.d/ there is nothing related to sound card neither how can i set the default alsa device to card 2 ? thanks!

  3. Hi, i have a live system running (Armbian on Orange Pi PC2). i found the Serial OTG on the microUSB is not work. and i didn't modified the image in the SD as described above before first boot. so now i only need to create the symbolic link in /lib/systemd/system as shown above? i checked there is nothing in my /etc/modules and no ttyGS0 in my etc/securetty and no serial-getty@.service in /lib/systemd/system any help here? thanks! Joseph

  6. hello i just install the latest armbian on orange pi pc2 board, the kernal is already 4.14 therefore the OTG function should be there. root@orangepipc2:~# dmesg |grep musb [ 1.323924] musb-hdrc musb-hdrc.1.auto: MUSB HDRC host driver [ 1.323939] musb-hdrc musb-hdrc.1.auto: new USB bus registered, assigned bus number 9 [ 1.324416] usb usb9: Manufacturer: Linux 4.14.78-sunxi64 musb-hcd [ 1.324421] usb usb9: SerialNumber: musb-hdrc.1.auto however, i cannot enable the usb serial over OTG. anyone can show me how to do it? i tried it on debian and windows but both has nothing when i connect to the OTG port. thanks very much!
