Hi all,

I first installed the KX Studio repositories, and later I updated to the full KX Studio (kxstudio-desktop and kxstudio-meta-all), but now there's no sound. In the alsamixer I have turned all the volume sliders for my soundcard (M-Audio 2496) up, except for some called <Multi Tr> where it's not possible. And also in the Mudita24 (Eny24) the two analog volume sliders are turned up.

I'm running Mint MATE Rebecca 17.1, and the inbuilt soundcard is HDA Intel. Maybe that should be set as the 2nd soundcard, and M-Audio as the 1st?

Any help appreciated..

(Lydkort = sound card)

My guess is that pulseaudio (that I think is a default package on Mint) is still handling your devices. Check your Audio Devices control panel for your system (that should be more or less a front for pulseaudio). You might also try pavucontrol or some other software like that. These tools should make you able to select a default soundcard for your laptop. When using jack you don't actually need it. Just select your soundcard for the devices fields in qjackctl.

Thank you. The thing is that after installing KX studio, the standard sound preferences panel is gone (When I click the Menu > Sound and video > Sound, a small window pops up saying "Waiting for Sound System to respond", and it keeps staying there until I click Cancel), and Qjackctl has changed so that the field where you choose your soundcard is no longer there.

The software manager says I have pavucontrol installed, but what's its name under Applications? I tried to open 'Volume control for Pulseaudio' but got this message: "Fatal error: Unable to connect to Pulseaudio: OK".

The error msg means that pulseaudio isn't running.

To start Pulse, open a terminal
Now your pavucontrol and similar should work and you can switch between audio devices.

If you want to stop Pulse

The field is now moved to the new 'Advanced' tab on the main panel.
Along with releated items. That's faked out a lot of people. Still wakes me up on occasion.
Cheers

Thank you, I've started pulseaudio now, and everything looks right in the preferences. And I've chosen my soundcard in Qjackctl (that 'Advanced' tab had escaped my eyes too! ), then quit Qjackctl and started it again.

But, except from the system's loudspeaker test, there's still no sound..

Also, in Qjackctl under Connect > Audio, my soundcard isn't present.

In Cadence under 'Alsa Audio Bridge Type' I have it set for ALSA -> Loop -> JACK, and under Pulseaudio it says "Pulseaudio is started but not bridged".

When I play a file with Kid3 (a tag-editor with a player) I get this message:

KDE detected that one or more internal devices were removed.
Do you want KDE to permanently forget about these devices?
This is the list of devices KDE thinks can be removed:

Output: M Audio Audiophile 24/96 (ICE1712 multi)

EDIT: I can play music and videos from the Internet and with other players on my PC now, so actually it's only VLC and Kid3 and the sequencers on my computer that won't play any sound..

I've just re-installed Kid3, and it also plays sound now. So it's only the sequencers that won't. The connections are right in Qjackctl, so I wonder why. I have tried with both Rosegarden, Qtractor, and Ardour.

EDIT: Now streaming from the Internet gives no sound neither. That is, the music / videos are played, there's just no sound. Pulseaudio is running, and Flash player is activated, don't know what else is needed..

EDIT 2: Now I have sound again from Internet. I installed Opera to see if that one gave sound (which it did), and afterwards Firefox also did. So since it's only the sequencers that are totally silent, I guess it must be a problem with Jack. But all the settings look right.

In Cadence under 'Alsa Audio Bridge Type' I have it set for ALSA -> Loop -> JACK, and under Pulseaudio it says "Pulseaudio is started but not bridged".

This probably means that the package "pulseaudio-module-jack" is not installed.

Make sure that you select the right audio card in the configuration panel. Once jack is started, take a look at
Catia (Cadence tools) and you should see the system playbacks and captures
(system refers to the audio interface, whichever jack is using) and the
Pulseaudio Jack Sink, which should be connected to the system playbacks.

I am not familiar with Linux Mint or KDE, but somewhere in the sound system settings (or else, try pavucontrol)
you have to select the Jack Sink for the sound of desktop applications. I always forget this last step in the rare
cases in which I need jack apps and desktop apps to produce sound at the same time.

Thanks, I've installed the "pulseaudio-module-jack" now, and Cadence says Pulseaudio is brigded to Jack.

in Catia it's the Pulseaudio Jack Source (not "Sink") that is connected to the system playbacks. I see no Sink, only System Playback+Capture 1-2, and Jack2alsa + alsa2Jack, Playback+Capture 1-2.

In pavucontrol, the data out- and in units are both set for Jack Sink (Pulseaudio), but I see no options for selecting the "Jack Sink for the sound of desktop applications" anywhere?

Btw, there is no sound from ANY program now

Also, in Qjackctl > Setup > Options, I've put these two scrips:

pacmd load-module module-jack-source channels=2; pacmd load-module module-jack-sink channels=2;

and

pulseaudio -k

like here:

https://sites.google.com/site/nueusx/jack-pulse.png

and restarted, but still no sound...

In pavucontrol, the data out- and in units are both set for Jack Sink (Pulseaudio), but I see no options for selecting the "Jack Sink for the sound of desktop applications" anywhere?

You already did it. I meant "Desktop applications" such as firefox or the desktop media player in contrast to "music/audio oriented applications" such as ardour or rosegarden. The former use pulseaudio as a sound system, the latter use jack. Pavucontrol manages pulseaudio, qjackctl or Cadence manage Jack.

To narrow down the sources of your problem I suggest leaving out pulseaudio and jack for a moment and use some basic tools to test the sound.

First of all, quit qjackctl, and Cadence, and pavucontrol. Avoid pulseaudio autospawn and kill the sound servers:

echo autospawn = no >> ~/.config/pulse/client.conf
killall -9 jackd jackdbus pulseaudio

(Issue twice the last command, to check the three processes are not found)

Then, open mudita24 again.
In the Analog Volume tab, make sure there are DAC sliders and they are up.
In the Patchbay/Router tab, make sure that H/W Outs are set to PCM Outs.

Now, check again the card number with

cat /proc/asound/cards

Assuming it is number two, as it was when you showed the output of aplay -l, do the speaker test:

speaker-test -Dhw:2 -c2 -twav

where -Dhw:2 means the card number 2
-c2: Two channels
-twav: A test consisting of a female voice saying "front left, front right"

Does it make sound? Is there any problem so far?

Assuming it is OK, decide on what tool you want to use to manage jack. It is qjackctl or Cadence, but not both.
As you have installed KXstudio, the natural and wise choice is Cadence.
Ah, and don't worry about that pacmd command in qjackctl scripts. It is not needed
(it was needed in the past to load the pulseaudio jack sink and source, from qjackctl, but not anymore,
and anyway, you are going to use Cadence, aren't you?).

Now, restart pulseaudio

pulseaudio --start

And start again with Cadence: Choose the right audio card, start Jack, start the pulseaudio bridge. What do you see in Catia?

If nothing seems to work, show the output of this informative command:

jack_lsp -c

It will also help a screenshot of Cadence showing the panel you get when you press Configure: Driver tab

Cheers, Pablo

Oh, good

I quit qjackctl, and Cadence, and pavucontrol, and did the commands:

I did the speaker test, but heard no voice. Here's the output:

tl@tl-P5Q-SE ~ $ speaker-test -Dhw:2 -c2 -twav

speaker-test 1.0.27.2

Which in my humble translation means:

Playback unit is hw:2

WAV-files
Sound test format not accessible for playback: Invalid argument
Could not set hwparams: Invalid argument

Yes, I'll use Cadence, but now I guess the hwparams must be set, before I continue?

EDIT. I've just chosen my sound card in sound preferences and Cadence's Jack settings, and now there's sound from the players But still no sound from the sequencer (Ardour)

Playback unit is hw:2
Current parameters are 48000Hz, S16_LE, 2 channels

Oops, it works in my box but try without "-twav". It should produce pink noise.
By the way, you can tell the terminal to print in English, this is:

export LANG=C
killall -9 jackd jackdbus pulseaudio
speaker-test -Dhw:2 -c2

Yes, I'll use Cadence, but now I guess the hwparams must be set, before I continue?

Try the above first. I think it should work

EDIT. I've just chosen my sound card in sound preferences and Cadence's Jack settings, and now there's sound from the players But still no sound from the sequencer (Ardour)

I suggest that before trying with Ardour, you should make sure that playback through jack works. For example, if you put some mp3 or wav file in your home directory (just to make the command simpler), say "song.mp3".

mplayer -ao jack song.mp3

Or you can use audacious with the jack output plugin, or aqualung.

And what

jack_lsp -c

says?

On the other hand, in the system sound preferences (the same as in pavucontrol) you should choose the Jack Sink for playback once jack is started and the pulseaudio bridge is up. Otherwise, the "normal" players won't make sound once Jack has grabbed the Maudio.

By the way, I am assuming that you want to use the M-audio card for everything and the onboard audio card is not used at all, am I right?

Okay, thanks. Here are the outputs:

Is jnd.mp3 right under your home directory? Copy the file there just for this test.

The above command will list your jack ports and connections.
It only makes sense when jack is running. It is like a Catia screenshot, in pure text.

I can neither open the system sound preferences (it just says "waiting for sound system to respond") nor the pavucontrol.

Oh,
because pulseaudio autospawn is off you have to start pulseaudio manually with

pulseaudio --start

To avoid this, delete the line

autospawn = no

in

~/.config/pulse/client.conf

(.config is a hidden directory in your home, so Control-H, show hidden directories,
and navigate to pulse directory, then client.conf file, open with your default text editor,
and delete the line).

"speaker-test -c2" generates no sound neither. Here's the output:

Okay I have started Jack now in Cadence, and also in Cadence > Configure I have chosen my M-Adio soundcard. (https://onedrive.live.com/embed?cid=E50 ... 89AgORkRZk)

I've deleted "autospawn = no" from ~/.config/pulse/client.conf, so the file now is empty.

Both the system sound preferences and pavucontrol look right now, with Jack Source and Sink as Input and Output, respectively, but there's no sound from any program..
