Hello All,

I have some queries related to the Audio driver.

I am working on a PXA270 refrence board. We have a Wolfson 9714 chip on
our board. We also have got a driver for the same from Wolfson, which
we have integrated in our OS configuration.
Now the problem is that when the OS image gets loaded, I distinctly
hear the Startup sound from the Headphones.But after the complete OS
image gets loaded and when I try to play some MP3 songs or any other
audio files the sound is very low ... I am not sure which setting is
causing this to happen, since we are sure that the hardware is fine
since I get the loud startup sound ... I most probably think that the
GWES thread is configuring some different audio setting ... If anyone
has encountered this kind of problem before then if he could provide
any pointers as to what could be the source of problem it would be a
great help ...!

Regards,
Swapnil.

Make sure you check the simple things like - Is the mp3 you're testing with
have a very low volume? Can you change the volume with the control panel
applet? Is the amplifiier being turned on? By whom?

Hello Todd,

Thanks for your reply ...!

I did check the things as suggested by you ... However the mp3 that I
am testing with does not have a low volume ... I can notice a change in
the volume when I change the volume with the control panel applet ...
but even when the control panel applet volume is at maximum the audio
is barely audible ... However I did not check about the amplifier ...
Can you please tell me as to where can I find the setting related to
the audio amplifier ... May be that might be causing the problem ...
:-) ...!

Looking forward for your reply ...!

Regards,
Swapnil.

Hello All,

I have found some new observations regarding the audio query that I had
...!

I found that the function sndplaysound() which is used to play the
Startup sound in WinCE 5.0 is actually reducing the volume after it
plays the Startup sound. I also tried not to play the Startup sound and
then listen to the MP3 if it gets played at a proper volume ... but it
did not help ... the sndplaysound function is used to notify about the
various events as well such as opening an application, minimizing and
maximising a windows etc., so if I do any of the above the sound is
heard at a higher volume and then it again goes to the lower volume ...


I am not sure how this function,i.e. sndplaysound is configuring this
setting ... ?

Regards,
Swapnil.
