Hi maemo forum,

my N900 keeps on muting the earpiece speaker during a 2G/3G voice call.
It works with the build in speakers, as well as with connected external headphones.

i have noticed that in the alsamixer the gain setting for

- Headphone gain = -59.9 dB
- Earphone gain = mute
- Earphone off

i have adjust the settings correctly(0 dB gain), but still no sound on the build in earpiece speaker (i also tried to save the alsa setting with alsactrl store and reboot).

i have the same behaviour with the stock nokia kernel (2.6.28-omap1) and the the 2.6.28-power50 kernel.

any suggestions are highly welcome, since this bug makes the phone pretty unusable.

thx,
p.
