Does the bard’s Jack of All Trades feature make them proficient with thieves’ tools?

PHB describes the Jack of All Trades feature as

you can add half your proficiency bonus, rounded down, to any ability check you make that doesn’t already include your proficiency bonus

It also says that

trying to open a lock requires proficiency with thieves’ tools

Assuming that Jack of All Trades does not give you proficiency in any skill that you are not proficient in, does it mean a bard actually can NOT pick a lock?

How does Jack of All Trades interact with Reliable Talent?

The Bard’s Jack of All Trades says you can add half of your proficiency bonus to rolls to skills that you otherwise can’t add your proficiency bonus. And the Rogue’s Reliable Talent feature lets them roll a minimum of 10 on any skill that benefits from their proficiency bonus.

So if I am a Rogue 11/Bard 2, does the half-proficiency from JoAT let me roll a minimum of 10 on ALL skills via Reliable Talent, or does half the proficiency bonus not count as activating Reliable Talent?

Jack Audio Service and Surround Audio Systems

I use Ubuntu Studio 19.04.

I’ve been experimented with Jack Audio Service and I have a doubt about the Audio Connection Panel:

Whatever the configuration I use, I don’t have any reference to my physical 7.1 surround sound card, which is an Intel Corporation 6 Series/C200 Series Chipset Family HDA_Intel, included inside the H61M-P31/W8 (MS-7788) Motherboard.

I just get this:

My Jack Audio Connections Panel

As you can see, there is not any reference to the front, rear or side audio channels.

So… What’s wrong here?

Or… What had I missed to do?

Does Bard’s Jack of All Trades grant them greater initiative?

Bards get the ability “Jack of All Trades” which reads:

Starting at 2nd level, you can add half your proficiency bonus, rounded down, to any ability check you make that doesn’t already include your proficiency bonus.

Since your initiative roll is based purely on your dexterity, and it says “ability check” and not “skill check”, does that mean that a Bard, starting at 2nd level, will tend to have better initiative than others?

Ubuntu, jack, maximum priority for audio application

OS, apps and hardware info

Linux local 5.0.0-23-lowlatency #24-Ubuntu SMP PREEMPT Mon Jul 29 16:17:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux jackdmp version 1.9.12 tmpdir /dev/shm protocol 8 Bitwig-studio version 3.0.1 USB2 Audio interface Tascam US16x02 


Is possible run audio application with max priority for this application? For best performance and lowest latency without cruckling/buffer problem for audio application.


I reinstalled Ubuntu studio 19.04, update, upgrade, install DAW Bitwig studio 3.0.1, then install indicator-cpufreq (for changing my cpu to best performance).

Then I ran jackd in this configuration.

/usr/bin/jackd -dalsa -dhw:US16x08 -r44000 -p128 -n2 

I select in indicator-cpufreq applet Performance (for best performance), then checked via lscpu it is working.

Model name:          Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz CPU MHz:             3455.159 CPU max MHz:         3500,0000 CPU min MHz:         400,0000 NUMA node0 CPU(s):   0-3 

Then I ran Bitwig studio. I tried do load some my older project.


When play the music in DAW, there are some crackling during the playing, and when I do something in DAW during playing (for example zooming or moving only), crackling is even worst.

Jackd log shows me many xruns.

I swear I had same configuration before reinstall OS and it was OK for this configuration, no crackling at all during playing even when working in DAW during playing or recording.

I tried install older versions of Ubuntu studio, no effect, crackling still present, same.

Why is now crackling due playing in DAW? Applet indicator-cpufreq changed to best performance, but seems not for DAW, no effect for CPU load in DAW when I selecting between Performance and Powersave in indicator-cpufreq, but lscpu shows me different CPU MHz.

What is the magic? Before I reinstalled OS, everything works fine. I found something about nice utility. Is it what I need to setup?

Thank you very much for any informations.

Sound from blutetooth but not aux jack

I have a new mini PC running Ubuntu 19.04. I can get bluetooth to work fine with external speakers (JBL Flip4) but my system can’t see the audio jack. Amixer will not show me simple controls for headphone or speakers.

Jack Audio – Headphone port

I run Ubuntu Studio 19.04 on a HP AMD laptop. I am relatively novice at linux.

I am using Jack audio to run sound for SuperCollider, Ardour, PureData etc.. and I am bridging it to system (puluseaudio sink/source) using ‘ubuntu studio control’

I get sound from the speakers but not from headohones even when I restart jack after inserting headpohones. The only way I get sound on headphone port is if I boot with headphones connected.

Is this a Ubuntu Studio/Jack/PulsuAudioBridge bug or could there be a problem on my end?

Please help me
