Linux Could not initialize audio device

jobe · 2012-07-24 09:21

Hi all,

I am using opdenkamps Eden-pvr version of xbmc together with xvdr.
When I select Sync Audio and Video I am getting above error when switching channels in live tv (not every time, but most times). After the error occured I have to restart xbmc to get audio to work.

When I turn off AV Sync everything is working fine. Unfortunately the video is running smoother when AV Sync is turned on, so I would like to use this setting. Anyone is experiencing the same?
Any idea why this happens?

Kind Regards,
Jobe

looks like I found a solution

Here is my hw configuration:

Code:

**** List of PLAYBACK Hardware Devices ****

card 0: NVidia [HDA NVidia], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

card 0: NVidia [HDA NVidia], device 1: ALC662 rev1 Digital [ALC662 rev1 Digital]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

and here is my asound.conf enabling all 3 devices:

Code:

pcm.!default {

        type plug

        slave {

                pcm "both"

        }

}

pcm.both {

        type route

        slave {

                pcm multi

                channels 6

        }

        ttable.0.0 1.0

        ttable.1.1 1.0

        ttable.0.2 1.0

        ttable.1.3 1.0

        ttable.0.4 1.0

        ttable.1.5 1.0

}

pcm.multi {

        type multi

        slaves.a {

                pcm "tv"

                channels 2

        }

        slaves.b {

                pcm "receiver"

                channels 2

        }

    slaves.c {

        pcm "analog"

        channels 2

    }

        bindings.0.slave a

        bindings.0.channel 0

        bindings.1.slave a

        bindings.1.channel 1

        bindings.2.slave b

        bindings.2.channel 0

        bindings.3.slave b

        bindings.3.channel 1

    bindings.4.slave c

    bindings.4.channel 0

    bindings.5.slave c

    bindings.5.channel 1

}

pcm.tv {

        type dmix

    ipc_key 1024

    slave

    {

        pcm "hw:0,3"

        period_time 0

        period_size 1024

        buffer_size 4096

        rate 48000

        channels 2

    }

}

pcm.receiver {

type dmix

        ipc_key 1025

        slave

        {

                pcm "hw:0,1"

                period_time 0

                period_size 1024

                buffer_size 4096

                rate 48000

                channels 2

        }

}

pcm.analog {

type dmix

        ipc_key 1026

        slave

        {

                pcm "hw:0,0"

                period_time 0

                period_size 1024

                buffer_size 4096

                rate 48000

                channels 2

        }

}

and finally I changed

Code:

<audiodevice>default</audiodevice>

to

Code:

<audiodevice>alsa:default</audiodevice>

in guisettings.xml.

Not sure if everything is really necessary, right now I do not have any problems with initializing the audio device (keep my fingers crossed).

Kind Regards,
Jobe

And just for completeness, my old asound.conf (NOT WORKING!!)

Code:

pcm.!default {

    type plug

    slave {

    pcm multi

    rate 48000

         }

         ttable.0.0 1.0

         ttable.1.1 1.0

         ttable.0.2 1.0

         ttable.1.3 1.0

}

#ctl.!default hdmiout

pcm.analog {

        type hw

        card 0

        device 0

}

ctl.analog {

        type hw

        card 0

        device 0

}

pcm.hdmiout {

        type hw

        card 0

        device 3

}

ctl.hdmiout {

        type hw

        card 0

        device 3

}

pcm.multi {

        type multi

        slaves.a.pcm "hdmiout"

        slaves.a.channels 2

        slaves.b.pcm "analog"

        slaves.b.channels 2

        bindings.0.slave a

        bindings.0.channel 0

        bindings.1.slave a

        bindings.1.channel 1

        bindings.2.slave b

        bindings.2.channel 0

        bindings.3.slave b

        bindings.3.channel 1

}
