AirPlay skipping sound with Tinkerboard + HifiBerry DAC

I’ve got a brand new ASUS Tinkerboard with a HifiBerry DAC+ Pro, running on Volumio 2.349. Audio playback is fine from local files or files from a NAS, but playback via AirPlay gives skipping sound (music for a second or so, then a break of 1 or 2 seconds, etc.). AirPlay works fine if I use the built-in headphones out on the Tinkerboard instead of the HifiBerry. The issue is thus isolated to AirPlay via HifiBerry DAC.

I tend to believe this is a software issue, because the Tinkerboard + HifiBerry DAC work well with playback from local files and NAS files.

Any ideas what is going on? Is this a bug? Any ideas how to dig deeper to understand the source of the problem?

Hi, have you found a solution to your problem? I had the same issue with AirPlay using a HifiBerry DAC+ compatible board, and found the solution from the following webpage:
nw-electric.way-nifty.com/blog/2 … sync-.html

Basically, just need to modify an AirPlay configuration file.

$ nano /volumio/app/plugins/music_service/airplay_emulation/shairport-sync.conf.tmpl

Make the following changes, save the file, and reboot.

general =
{
name = “${name}”;
interpolation = “soxr”;
log_verbosity = 0;
};
alsa =
{
output_device = “hw:1,0”;
mixer_device = “hw:1”;
mixer_control_name = “Digital”;
output_format = “S32”;
output_rate=44100;
period_size=4410;
buffer_size=22050;
};
sessioncontrol =
{
run_this_before_play_begins = “/usr/bin/mpc stop”;
allow_session_interruption = “yes”;
};
