Jack <-> alsa connectivity

[sadko4u]

The short description: I need to route the signal from an ALSA application to JACK and back.
According to this manual: https://jackaudio.org/faq/routing_alsa.html
I've performed the following configuration:

Code: Select all

pcm.rawjack {
    type jack
    playback_ports {
        0 system:playback_1
        1 system:playback_2
    }
    capture_ports {
        0 system:capture_1
        1 system:capture_2
    }
}

pcm.jack {
    type plug
    slave { pcm "rawjack" }
    hint {
 	description "JACK Audio Connection Kit"
    }
}

aplay on 'rawjack' device works well but aplay on 'jack' always gives repeating noise.
Trying to configure the default device:

Code: Select all

pcm.!default
{
    type asym
    playback.pcm {
        type plug
        slave.pcm "rawjack"
    }
    capture.pcm {
        type plug
        slave.pcm "rawjack"
    }
}

GIves the repeating noise for any application when trying to play the audio.

For gmplayer, I see in console:

Audio device got stuck!
A: 0.0 (00.0) of 845.0 (14:05.0) ??,?%
Audio device got stuck!
A: 0.0 (00.0) of 845.0 (14:05.0) ??,?%

What I am doing wrong?

I can't find a configuration error. I used the same until I noticed that installing Pulseaudio already sets up a redirection from ALSA to Pulseaudio. Since I use jack_sink in Pulseaudio I don't need a separate ALSA-to-JACK redirection.

Do you have Pulseaudio installed? Maybe it messes with your .asoundrc.
