Thanks for the support of LOS on the Poco F3


The default minimum volume settings are a bit too high as the Poco F3 has some powerful speakers.
I suggest lowering the volume values in audio_policy_volumes.xml and default_volume_tables.xml.
These values worked fine for me...
audio_policy_volumes.xml:
<volume stream="AUDIO_STREAM_VOICE_CALL" deviceCategory="DEVICE_CATEGORY_SPEAKER">
<point>0,-3600</point>
<point>33,-2400</point>
<point>66,-1200</point>
<point>100,0</point>
</volume>
<volume stream="AUDIO_STREAM_VOICE_CALL" deviceCategory="DEVICE_CATEGORY_EARPIECE">
<point>0,-3600</point>
<point>33,-2400</point>
<point>66,-1200</point>
<point>100,0</point>
</volume>
<volume stream="AUDIO_STREAM_RING" deviceCategory="DEVICE_CATEGORY_SPEAKER">
<point>1,-4455</point>
<point>33,-3015</point>
<point>66,-1530</point>
<point>100,0</point>
</volume>
<volume stream="AUDIO_STREAM_ALARM" deviceCategory="DEVICE_CATEGORY_SPEAKER">
<point>1,-4455</point>
<point>33,-3015</point>
<point>66,-1530</point>
<point>100,0</point>
</volume>
<volume stream="AUDIO_STREAM_NOTIFICATION" deviceCategory="DEVICE_CATEGORY_SPEAKER">
<point>1,-4455</point>
<point>33,-3015</point>
<point>66,-1530</point>
<point>100,0</point>
</volume>
default_volume_tables.xml:
<reference name="DEFAULT_SYSTEM_VOLUME_CURVE">
<!-- Default System reference Volume Curve -->
<point>1,-3120</point>
<point>33,-2340</point>
<point>66,-1560</point>
<point>100,-780</point>
