Jack stopped working with firewire soundcard since kernel 4.1.8

phste · 2015-09-26 22:05:09

Hi,

I recently installed a fresh Arch x64 onto my computer. I started to use the system with the linux-lts kernel, which was version 3.14 then.

Connected to my computer I have a Focusrite Saffire Pro 40. The card was used by jack2 and then piped to pulseaudio with the module "pulseaudio-jack".
Everything worked fine until linux-lts was updated to kernel verison 4.1.8. Since then jack is not starting with the exact same configuration, which is basically the standard configuration for any firewire card.

This is the output when I try to start jack with qjackctl.

At first I recognized that the firewire card was captured by PulseAudio. To see if PulseAudio was the cause I told PulseAudio to ignore the card via this udev rule:

SUBSYSTEMS=="firewire", ENV{PULSE_IGNORE}="1"

But disabling PulseAudio capturing the card was not the cause, the errors were still the same. I don't find a solution to this problem other than downgrading the kernel back to 3.14.
And I don't want to downgrade to a now not-supported kernel.

Here is some other output from the ffado-test tool

Give alsa (via QJackCtl) a try. That device should be supported via alsa since about a year. You won't need ffado that way. With the newest pulseaudio it should automatically create jack sinks when it is started.

Unfortunately it did not work. ALSA is also complaining

PulseAudio did recognize the device before I banned it, unfortunately it did recognize it as a surround device so all the bass was missing on headphones.
Moreover it stopped working after a random time. I also use the device for playing with my bass guitar.

BenderRodriguez · 2015-09-27 12:16:55

Try something like 512 frames/period with 2 buffers. If that doesn't work play around with these settings.
16 frames doesn't work for me either. I'm using a StudioKonnekt 48 btw. This device is also build upon the DICE chipset.
In rare cases another jack instance may hang and lock the device. Hence, restarting it with qjackctl will give an error message "Failed to acquire device name...". You need to kill the hanging instance if that happens.

Thank you, really! ALSA is working now and shown via PulseAudio Jack Sink.

Only problem after about 30 seconds of listening to music it suddenly stops with this error in the qjackctl logs, maybe you have a clue.

BenderRodriguez · 2015-09-27 19:35:58

Hmm, no clue about that error message. Could be a driver problem? Try to experiment with these buffer settings. Larger values should be more stable but result in longer latency. Smaller values allow for software monitoring but are less robust against buffer underruns.
Furthermore, you probably want to use/tick the RT/realtime option.
