Hi
I recently have a problem when recording : signals from my sound card output ports 1 & 2 are not received in ardour. (system.capture_1 and system.capture_2 showing no input signals)
I already checked with a live Ubuntu-Studio session on this computer and all inputs are well received by ardour in Ubuntu-Studio live session. So it is not a material default.
The pb seems coming from my istalled ardour configuration.
My question : Is there a way to reset ports assignments and settings to default in ardour ?
Thanks for your answers, best musical wishes to you all.
So the inputs show (Window > Recorder) shows the inputs, but they are silent?
If so check perhaps the hardware mixer of the device. In a terminal window run alsamixer. <F6> to select the soundcard, <F4> to show inputs, and check levels and enable.
Hello Robin,
Thank you very much for your fast answer and good detailed advice, for a reason I still don’t know alsamixer shown one output of the sound card was set to zero.(Output Front in my case)
I only had to increase this parameter and could record again on the track 1 and 2.
You geek guy ! …
THANK YOU VERY MUCH ROBIN ! … Wish you a great summer !
When Linux shuts down, the mixer settings of all devices are saved (usually to /var/lib/alsa/asound.state, and on [re]boot those are restored for devices present in the system.
However this is not possible when hot-plugging USB devices. When disconnecting a device it’s too late to save the settings and also initially the state is unknown.
I guess you may have booted with the device present and that caused the mixer to be reset.
You can try to manually force a save sudo alsactl store.
One again many thanks for this interesting explanation Robin.
So yes, my pb certainly came from hot un-pluging my sound card.
By the way I visited your website, very impressive job you do !.. Congratulations !
Would you know if there is somewhere an actualized list of dedicated devices that working with ardour embeded ? or supporting to install on it ? … I would be very interested in buying a dedicated ardour workstation as soon my budget will allow it.
(Portable solution would actually perfectly fits my needs)
Yes, right, I asked because I remember seeing 3 or 4 years ago a presentation of a small console with ardour embedded … I though it can be more devices available nowadays …
I will search a bit more for this type of device and probably create a new thread dedicated to this request.
