this is a follow-up to a related thread.
Using Ardour5 for a couple of weeks on this PC, OS is Linux Mint, not using Jack, just ALSA. Ardour worked so far as usual. After a onfiguration change it stopped outputting sound.
Configuration changes before Ardour stopped outputting sound were:
- Removed a graphics card because Ardour’s UI responded with annoying lags and delays;
- switched to on-board graphics (Intel), Ardour’s UI responds now smoothly;
- sound output from mainbaord is now routed through the HDMI cable and played back on the monitors built-in speakers;
- reconfigured audio settings for OS; other audio stuff like Audacity or VLC works fine.
However, if I connect a 3.5" headphone directly to the mainboards line out, Ardour outputs audio on the headphones when I switch the OS audio settings to analog.
I assume Ardour does not use the same audio stack as other applications and that Ardour does not understand that the audio signal comes through an HDMI cable.
Output from Paul’s helper script:
$ bash adevices.sh ======================================== Part I: ALSA Advanced Linux Sound Architecture Driver Version k5.3.0-51-generic. Card 0 (PCH): * Playback Device 0 (ALC887-VD Analog): - Subdevice 0 (hw:PCH,0,0): closed * Playback Device 3 (ALC887-VD Digital): - Subdevice 0 (hw:PCH,3,0): closed * Playback Device 7 (HDMI 0): - Subdevice 0 (hw:PCH,7,0): closed * Playback Device 8 (HDMI 1): - Subdevice 0 (hw:PCH,8,0): closed * Playback Device 9 (HDMI 2): - Subdevice 0 (hw:PCH,9,0): closed * Recording Device 0 (ALC887-VD Analog): - Subdevice 0 (hw:PCH,0,0): closed * Recording Device 2 (ALC887-VD Alt Analog): - Subdevice 0 (hw:PCH,2,0): closed ======================================== Part II: jack processes
I don’t see a problem in Ardour’s mixer, and in Ardour’s Global Settings I can not find something related to sound output.
Where do I go from here?
Is there something like a troubleshooting checklist to work through if Ardour does not output sound on Linux?
