Jack stopped working after 1.5 years - no reason

Post by retnev »

After quite some time of Bliss, Jack just refuses to run.
Nothing new installed or removed for last 3 months.

It is almost impossible to know what causes it as the way developers document their work is largely unscientific and indeterminate .
I include an example from the logs for successful startup and failure to start.

What are the exact causes for Jack not to start.
The manual is utterly useless and the software is not properly characterised.

On first inspection this looks like an Alsa problem not finding the VSLinterface, but I checked with alsamixer and the interfface is detected with all inputs and outputs available, so the buck clearly stops with JACK.

On another topic. There is seemingly an alternative to Jack being developed. anyone know about it ?

Here are the logs with the sudden failure of jack to start:

Re: Jack stopped working after 1.5 years - no reason

Post by varpa »

You logs seem have "ERROR: JackServer::Open failed with -1" for both your "successful" and "unsucessful" starts which makes no sense.
You logs claim "ERROR: control open "hw:VSL" (No such device)" -- are you sure you device is working properly? Is the VSLinterface
a USB interface? If so, is it listed when you do "lsusb"?
Jack sometimes gets screwed up after computer is put in hibernation or if some other application (like a web browser) is using the audio device. This can be fixed by a reboot or closing the application using the audio device.

Another possibility: maybe you did a software update that broke something. If you can check what updates you have made (for example synaptic has a "history" menu option that shows the history of all updates), maybe you can revert updates back to a date when your card worked.

Re: Jack stopped working after 1.5 years - no reason

The reason was kernel version.

For some mysterious reason, my distro booted on a different kernel I did not specify.
there were no updates at all or any configs done.
The installation is basically locked down as it is mission crytical.
How that happened still baffles me. it booted on a liquorice kernel and not an older kernel I usually use.

Dead duck Alsa has its head up its $%& and only works with interfaces if you use very specific kernels.

Here I posted the solution and findings.
