Sorry about the confusion - I am interested in routing between the speaker and the phone speaker. The script you sent is for the wired headphone which the N900 automatically switches to once it detects a connected device.<br>

Hi Saurabh!<br>
<br>
You can use the following script for routing playback between speaker<br>
and headphones:<br>
<br>
#!/bin/sh<br>
<br>
if [ "${1}" == "speaker" ] ; then<br>
# low headphone playback volume<br>
amixer -qc0 cset iface=MIXER,name='Headphone Playback Volume' 5,5<br>
<br>
amixer -qc0 cset iface=MIXER,name='Left DAC_L1 Mixer Line Switch' off<br>
amixer -qc0 cset iface=MIXER,name='Left DAC_L1 Mixer HP Switch' on<br>
amixer -qc0 cset iface=MIXER,name='Right DAC_R1 Mixer Line Switch' off<br>
amixer -qc0 cset iface=MIXER,name='Right DAC_R1 Mixer HP Switch' on<br>
<br>
amixer -qc0 cset iface=MIXER,name='HP DAC Playback Volume' 50,50<br>
amixer -qc0 cset iface=MIXER,name='Speaker Function' 1<br>
else if [ "${1}" == "headphone" ] ; then<br>
amixer -qc0 cset iface=MIXER,name='Left DAC_L1 Mixer HP Switch' off<br>
amixer -qc0 cset iface=MIXER,name='Left DAC_L1 Mixer Line Switch' on<br>
amixer -qc0 cset iface=MIXER,name='Right DAC_R1 Mixer HP Switch' off<br>
amixer -qc0 cset iface=MIXER,name='Right DAC_R1 Mixer Line Switch' on<br>
<br>
amixer -qc0 cset iface=MIXER,name='HP DAC Playback Volume' 0,0<br>
amixer -qc0 cset iface=MIXER,name='Speaker Function' 0<br>
else<br>
echo 'Please specify option: "speaker" or "headphone"' ;<br>
fi<br>
fi<br>
<br>
Thanks, Daniil.<br>
