laptop confused: no sound with headphones in

by Atte

Hi I have a laptop running debian 10. Sometimes it gets confused with a mini-jack in headphones and mutes audio. It seems to be something automatic that goes wrong, since 1) pulling the mini-jack makes the sound come out of the speakers just fine (putting it back in mutes audio again etc)and 2) a reboot fixes it. I tried writing a script that un-mutes everything I can see and turns it up, but to no avail: amixer set 'Master' 100% unmute amixer sset -c 0 'Master' 100% unmute amixer sset -c 0 'Headphone' 100% unmute amixer set -c 0 'Speaker' 100% unmute amixer set -c 0 'PCM' 100% I'd like to know what's causing this and most importantly: any solution or work-around would be great! I know it's a long shot, but maybe someone can recognize this and point me in a more constructive direction? Cheers -- Atte http://latestyoutube.a773.dk | http://a773.dk

Re: [LAU] problem with zita-bridge to use two recording interfaces -- some extra info

by Fons Adriaensen

Hi Christoph,: > ... And I thought if I don’t run the rt-kernel, > I have to uncheck the realtime-setting in qjackctl, which may > be a misconception (?). It is. The standard kernel runs RT threads quite well. I've been using it on at least 20 Arch machines all doing audio work, and some of them quite heavy stuff with dozens of Jack clients and 64 channels in and out. No problems at all. Many of the original RT patches have been incorporated in the standard kernel for years now. You may need the RT kernel if you use very short audio periods, some people go as low as 16 frames.

Re: [LAU] problem with zita-bridge to use two recording interfaces -- some extra info

by Fons Adriaensen

Hi Christoph, Some extra info: In case your system does allow real-time, it could be that the maximum priority is set too low. Zita-ajbridge will run the thread talking to the ALSA device with a priority that is 10 higher than Jack's callback threads. So if your jack is configured for e.g. 80, and the system limit is 85, zita-ajbridge will fail. Ciao, -- FA

I suspect your system isn't configured to allow normal users running real-time threads. Zita-ajbridge will fail (silently, and yes that *is* a bug) if that is the case. The way to enable real-time for normal (non-root) users has changed on Archlinux some time ago, it now involves the realtime package (see the archwiki for details). I'm on Arch too but I'm still using the 'old' method without the realtime package. This just involves putting some lines in /etc/security/limits.conf: @audio - rtprio 95 @audio - memlock unlimited and making sure you are in the 'audio' group. If you do this you need to re-login after making the changes. AFAIK the realtime package is doing the same, but using a different group. Ciao, -- FA

problem with zita-bridge to use two recording interfaces

by soffioalcuore＠posteo.net

dear list members, I have a question on using zita-bridge with jack2, obviously I'm missing some detail (?). I'm trying to get two usb soundcards working as inputs for recording. as usual, I start jackd via qjackctl with one of them, say, the soundcraft notepad12fx as hw-device (with -r 48000 -p 512 -n 2). now, I want to add the 2nd interface, my zoom h4. in a terminal I put #zita-a2j -d hw:H4 -r 48000 -p 512 -n 2 I get #Starting synchronisation. and I can see the zita-bridge both in the graph window of qjackctl and in my daw (reaper). the problem is that I don't get any signal from the device connected by the zita-bridge. I have also tried to change both devices - without success. furthermore, I've tried to leave some of the parameters (-p and -n) out. am I missing something? thank you very much for any suggestion! have a good day!
