Latest update : Hifiberry Dac2 HD stops after playing one song

Since the latest Volumio update, I first got the message “failed to open alsa”. Fortunately with the help of the community I switched to headphones, rebooted and restarted again and this worked (meaning : I can listen to radio stations again). However, when I send my playlist on JRiver to Volumio it plays just one song (and not the complete list). When I send the same playlist to my Marantz streamer, it works perfectly. What should I do to play my playlist to Volumio (and playing the complete list and not just one song) ? What I don’t understand about Volumio : many problems last year with every update (‘failed to open alsa’ on Allo Boss and Hifiberry Dac 2 HD). Thanks in advance for your help.
