Problems with Audacity / Jack

Post by Scary Hallo »

Hello

since a few days a have a problem starting Audacity when jack is running. It takes more than one Minute until audacity comes up. And then even playback doesn't work. If I go to Preferences, I can see there is no input and no output device found. Host is set to jack.
The messages are like this

Code: Select all

bt_audio_service_open: connect() failed: Connection refused (111)
bt_audio_service_open: connect() failed: Connection refused (111)
bt_audio_service_open: connect() failed: Connection refused (111)
bt_audio_service_open: connect() failed: Connection refused (111)
Enhanced3DNow! detected
SSE2 detected
Without jack it works fine.

Hello Scarry Hallo,

Unfortunately Audacity <3! JACK :(
And the bt_audio_service_open message is probably related to Bluetooth, so maybe it helps to disable all Bluetooth related stuff.

Hmm, but it worked good. Unfotunately I've changed some settings when I was not running jack. I know "Never touch a running system". :evil:
So I think it's just a bug in my settings.
I'm using Audacity 1.3.9 with Ubuntu Studio 9.10
:?: :?: :?:

Apparently the bt_audio_service_open warning is related to the bluez-alsa package.

Now I removed the package bluez-alsa and the warnings are gone. But my main problem is still the same. Audacity needs 1 minute to start. I think it has something to do with jack settings.
:cry:

I can reproduce some of your problems.
On my netbook, running Ubuntu 9.10, a fresh install of audacity refuses to see a running jack (0.116), gives me "no devices" in the preferences, and doesn't show up as a jack client. I also get the "bt_audio_service_open" message. But audacity starts right away.

Hi there,

I think I have solved the case. I found a very old backup of the audacity.cfg and I changed the lines

Code: Select all

PlaybackDevice=ALSA: M Audio Delta 44: ICE1712 multi (hw:0,0)
RecordingDevice=ALSA: M Audio Delta 44: ICE1712 multi (hw:0,0)
to

Code: Select all

PlaybackDevice=JACK Audio Connection Kit: system
RecordingDevice=JACK Audio Connection Kit: system
It seems to work
:P

But that would mean that Audacity doesn't write it's own config file properly...
Mine says:

Code: Select all

[AudioIO]
Host=JACK Audio Connection Kit
No playback devices are listed. Looks like an Audacity bug. I don't use the program on this system anyway.

Yes that's also my opinion. I had

Code: Select all

[AudioIO]
Host=JACK Audio Connection Kit
and

Code: Select all

PlaybackDevice=ALSA: M Audio Delta 44: ICE1712 multi (hw:0,0)
RecordingDevice=ALSA: M Audio Delta 44: ICE1712 multi (hw:0,0)
Next week I plan to make some changes on my machine. Also a newer version of Audacity. I'll see what happens.
