Gian, I wonder if you've made any progress in tracking down your problem. Just to satisfy myself, I installed Ubuntu 14.04 LTS Desktop in VirtualBox and attached my external USB DAC to the virtual machine.
During the install I elected to include 3rd party software and updates. After the install I added the squeezelite package from the command line: Code: -------------------- sudo apt-get install squeezelite -------------------- Checked what sound devices existed on the system: Code: -------------------- chris@U14-VirtualBox:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 1: STAC9221 A1 Digital [STAC9221 A1 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: CODEC [USB Audio CODEC], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 -------------------- and Code: -------------------- chris@U14-VirtualBox:~$ squeezelite -l Output devices: default - Playback/recording through the PulseAudio sound server null - Discard all samples (playback) or generate zero samples (capture) pulse - PulseAudio Sound Server sysdefault:CARD=Intel - HDA Intel, STAC9221 A1 Analog - Default Audio Device front:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - Front speakers surround40:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - 4.0 Surround output to Front and Rear speakers surround41:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Digital - IEC958 (S/PDIF) Digital Audio Output dmix:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - Direct sample mixing device dmix:CARD=Intel,DEV=1 - HDA Intel, STAC9221 A1 Digital - Direct sample mixing device dmix:CARD=Intel,DEV=2 - HDA Intel, STAC9221 A1 Alt Analog - Direct sample mixing device dsnoop:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - Direct sample snooping device dsnoop:CARD=Intel,DEV=1 - HDA Intel, STAC9221 A1 Digital - Direct sample snooping device dsnoop:CARD=Intel,DEV=2 - HDA Intel, STAC9221 A1 Alt Analog - Direct sample snooping device hw:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - Direct hardware device without any conversions hw:CARD=Intel,DEV=1 - HDA Intel, STAC9221 A1 Digital - Direct hardware device without any conversions hw:CARD=Intel,DEV=2 - HDA Intel, STAC9221 A1 Alt Analog - Direct hardware device without any conversions plughw:CARD=Intel,DEV=0 - HDA Intel, STAC9221 A1 Analog - Hardware device with all software conversions plughw:CARD=Intel,DEV=1 - HDA Intel, STAC9221 A1 Digital - Hardware device with all software conversions plughw:CARD=Intel,DEV=2 - HDA Intel, STAC9221 A1 Alt Analog - Hardware device with all software conversions sysdefault:CARD=CODEC - USB Audio CODEC, USB Audio - Default Audio Device front:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - Front speakers surround40:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - 4.0 Surround output to Front and Rear speakers surround41:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - IEC958 (S/PDIF) Digital Audio Output dmix:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - Direct sample mixing device dsnoop:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - Direct sample snooping device hw:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - Direct hardware device without any conversions plughw:CARD=CODEC,DEV=0 - USB Audio CODEC, USB Audio - Hardware device with all software conversions -------------------- Edited /etc/default/squeezelite Code: -------------------- chris@U14-VirtualBox:~$ cat /etc/default/sysconfig cat: /etc/default/sysconfig: No such file or directory chris@U14-VirtualBox:~$ cat /etc/default/squeezelite # Defaults for squeezelite initscript # sourced by /etc/init.d/squeezelite # installed at /etc/default/squeezelite by the maintainer scripts # The name for the squeezelite player: SL_NAME="$(hostname -s)" # ALSA output device: SL_SOUNDCARD="*plughw:CARD=CODEC,DEV=0*" # Squeezebox server (Logitech Media Server): # Uncomment the next line if you want to point squeezelite at the IP address of # your squeezebox server.

I was not able to re-produce your error. Pulseaudio does not appear to be a problem. Perhaps your debug log will offer some clues. ------------------------------------------------------------------------ Krisbee's Profile: http://forums.slimdevices.com/member.php?userid=59080 View this thread: http://forums.slimdevices.com/showthread.php?t=101436 _______________________________________________ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
