[Q] Popping sound with Navigon on CM7.2RC1

Hello all,

I've been using CM7.1 and 7.2 Temasek's KANG for quite some time now, and it's working great.
I do have one annoying problem: when I use Navigon and enter a route, I get voice directions. After the voice stops speaking, you can hear the speaker being for a few seconds (hissing noise) and then the speaker shuts off. No problem there.

However, at random the speaker starts making (quite loud) 'popping sounds' at random intervals. The voice isn't trying to say anything at that time. Often it pops 3-4 times in a row, then it's quiet for several minutes.
If I use DSP Manger and select either option (enhance bass or the equalizer), then the 'popping'-sounds changes into a soft (old dial-up) modem-kind of sound. It's not very loud but you can hear it. It usually stops by itself, or it stops after so turn the volume up/down - and then it stops because of the 'beep' the speaker makes when changing the volume, not because of the volume change itself.

This does not happen on stock firmware. So it seems Navigon is 'leaking' sound somehow and with stock firmware that 'leaking' is just ignored and with CM it is turned into one sound (popping) or the other (modem-like). Since it can be affected with the DSP Manager, I'm also hoping there is some solution that can be applied or some work-around. Any suggestions would be greatly appreciated.

Do you still have the problem - or found a solution for it?

Im using mapfactor navigator and get all 3-4seconds a noisy sound, sometimes also in other apps. Somewhere i read its because 2 apps are using the sound chip, but i don't know if the problem is caused by cyanogenmod 7.2 or hardware issue :/ Im using android since 6 days and the first i did was flashing cyanogenmod :p
