Can anyone please help with a problem concerning the <br />loss of sound in a Debian Jessie system.<br /><br />Due to sound problems whereby sound was first okay, <br />then lost, then regained, then lost again when running vlc <br />on a sound file and also when running YouTube, the following was <br />done :-<br /><br />Pulseaudio was installed on Friday and <br /><br />% dpkg -l | grep pulseaudio<br /><br />gave <br /><br />ii pulseaudio 5.0-13 amd64 PulseAudio sound server<br />ii pulseaudio-module-x11 5.0-13 amd64 X11 module for PulseAudio sound server<br />ii pulseaudio-utils 5.0-13 amd64 Command line tools for the PulseAudio sound server<br /><br />% aplay -l<br /><br />gave <br /><br />**** List of PLAYBACK Hardware Devices ****<br />card 0: PCH [HDA Intel PCH], device 0: ALC887-VD Analog [ALC887-VD Analog]<br />Subdevices: 0/1<br />Subdevice #0: subdevice #0<br />card 0: PCH [HDA Intel PCH], device 1: ALC887-VD Digital [ALC887-VD Digital]<br />Subdevices: 1/1<br />Subdevice #0: subdevice #0<br />card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]<br />Subdevices: 1/1<br />Subdevice #0: subdevice #0<br />card 1: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1]<br />Subdevices: 1/1<br />Subdevice #0: subdevice #0<br /><br />Jessie was then re-booted and the sound then re-appeared.<br /><br />Also<br /><br />% ls /etc/pulse <br /><br />gave <br /><br />client.conf daemon.conf default.pa system.pa<br /><br />and<br /><br />% ls ~/.pulse <br /><br />gave <br /><br />259df95a2b75426bb6ef25f372b08be2-card-database.tdb<br />259df95a2b75426bb6ef25f372b08be2-device-volumes.tdb<br />259df95a2b75426bb6ef25f372b08be2-runtime@<br />259df95a2b75426bb6ef25f372b08be2-stream-volumes.tdb<br />3e0b1f6422592f67f9f012034c3323d0-card-database.tdb<br />3e0b1f6422592f67f9f012034c3323d0-default-sink<br />3e0b1f6422592f67f9f012034c3323d0-default-source<br />3e0b1f6422592f67f9f012034c3323d0-device-volumes.tdb<br />3e0b1f6422592f67f9f012034c3323d0-runtime@<br />3e0b1f6422592f67f9f012034c3323d0-stream-volumes.tdb<br /><br />Vlc was used to run a test sound file (soundfile.wav) and that ran okay.<br /><br />Sound also worked fine on YouTube.<br /><br />However,
the sound was then lost when trying to use vlc again on a sound file
and also was not present when trying to use sound with a Web browser.<br /><br />% vlc soundfile.wav<br /><br />gave <br /><br />VLC media player 2.2.6 Umbrella (revision 2.2.6-0-g1aae78981c)<br />[0000000000971608] pulse audio output error: PulseAudio server connection failure: Connection refused<br />[0000000000899118] core libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.<br />[0000000000971608] alsa audio output error: cannot open ALSA device "default": Device or resource busy<br />[0000000000971608] core audio output error: module not functional<br />[00007fcbdcc02b68] core decoder error: failed to create audio output<br /><br />This behaviour (i.e. sound first working and then not working) <br />is similar to what happened before the installation of pulseaudio on Friday.<br /><br />So the cause of the loss of sound remains a mystery, I'm afraid.<br /><br /><br /><br />
