jack Wont Start After arch linux System Upgrade.

[johnaweiss]

Not sure if i'm running jack1 or jack2.
Up to now, it's been running just fine.

I'm running alsa only. Pretty sure i do not have pulse installed.

Here's the error log from qjackctl:

Does not seem an issue with jack, likely you just need to rebuild it.
This message:

libcelt0.so.2: cannot open shared object file: No such file or directory

implies that jack is not part of your system and built manually. so now the system libraries updated and created a mismatch of versions.

I also run jack on archlinux and see the messages

could not open driver .so '/usr/lib/jack/jack_firewire.so': libffado.so.2: cannot open shared object file: No such file or directory
could not open driver .so '/usr/lib/jack/jack_net.so': libcelt0.so.2: cannot open shared object file: No such file or directory

I am still able to use jack as my audio driver in programs like Ardour and Hydrogen. So on my machine things work in spite of not having those shared libraries.

I would guess the following diagnostic is pointing to your problem:

open "hw:H1" (No such device) ALSA lib pcm_hw.c:1829:(_snd_pcm_hw_open) Invalid value for card ALSA lib pcm_hw.c:1829:(_snd_pcm_hw_open) Invalid value for card ALSA: Cannot open PCM device alsa_pcm for playback.

I am not familiar with the syntax 'hw:H1'. That does not work on my machine and I see a similar error message. If I instead use 'hw:1' things work.

@ksralgp Do you mean i should change that string in the source, and recompile?

thx

[ksralgp]

I have no experience in qjackctl, but poking around it looks like you can set the device name in the "setup" menu. There is an "interface" box. I entered "hw:1" there and was able to start jackd. Alternatively it has a pull-down that shows you the devices it detected. Maybe you need to select something else there?

[johnaweiss]

Thx, i'll try that. So, the issue is a device is named that jack can't find? Does jack require any devices at all, to start?

However, without doing that (or anything else different), I noticed sometimes jack runs, sometimes it doesn't. Seem intermittent, or only works under just-so conditions or sequence of events (which i can't tell yet).
