Asterisks locks alsa device if chan

Asterisks locks alsa device if chan_alsa is loaded

I am implementing an extension 900 which routes the audio to alsa device. I am also using mpd which plays music through alsa.

Asterisk 15, Openwrt 18.06

mpd.conf

>> cat /etc/mpd.conf 

log_file "syslog"



bind_to_address "127.0.0.1"

bind_to_address "192.168.1.18"



input {

    plugin          "curl"

}



audio_output {

    type            "alsa"

    name            "sun4icodec"

    device          "hw:0,0"

    mixer_control   "Power Amplifier"

}

Here is the section of extensions.conf related to the extension

;SIP 900

exten => 900,1,NoOp(Testing calls to speakers. Dialing ${EXTEN} from ${CALLERID})

same => n,System(kill -9 `pgrep mpg123`)

same => n,System(amixer set 'Power Amplifier' 80%)

same => n,System(/usr/bin/aplay /var/lib/myapp/sounds/tone3.wav &)

same => n,System(sleep(4))

same => n,NoOp(Testing calls to speakers. Dialing ${EXTEN} from ${CALLERID})

same => n,Dial(CONSOLE/ALSA)

same => n,Hangup()

same => n,System(sleep(1))

same => n,System(amixer set 'Power Amplifier' 80%;)

same => n,System(sleep(4))

When chan_alsa is loaded it locks the alsa device and when something is played on mpd I get the following error

aplay: main:722: audio open error: Resource busy

I came across this on a website but I am not sure how to implement this. Can please guide me how to solve this… twiddle software and/or hardware mixing

output_device = Indicates the name of the ALSA
device to use for playing sound, i.e. for listening. A device name
specified here is passed, unchanged, to the ALSA sound layer, so any
ALSA device name should work. Warning : Asterisk may lock the ALSA
device specified here for the entire duration the Asterisk process is
running. You may have to twiddle software and/or hardware mixing
settings to keep Asterisk from hogging your output device.
