Hi, For calls, how to change from loud speaker to normal ear speakers on HTC devices with WM6? Tried using "pjsua_set_snd_dev ();" it returns "Unknown error". How to retrieve all available playback or output devices? Thanks. Calvin

Hi, oh, i did the listing out of sound devices, refering to the sndinfo.c sample. selected a different playback device from the list using "pjsua_set_snd_dev ();" yet the audio is still coming out from the rear speaker. I tested many other voip clients (Skype, Tivi, SJPhone) on WM, I wonder how they route it successfully to the ear speakers. Thanks.

Probably a "bit" of reverse engineering "for compatibility purpose" (that's legal) would be required on those products.

Hi, Accidentally found this: Programmatically Activating Speakerphone - http://www.peterfoot.net/ProgrammaticallyActivatingSpeakerphone.aspx Controlling the speakerphone - http://www.teksoftco.com/articles/article%20006/speakerphone.htm (from http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1594856&SiteID=1) Regards, nanang On Fri, Oct 10, 2008 at 4:33 PM, Fabio Pietrosanti (naif) <lists@infosecurity.ch> wrote: > Probably a "bit" of reverse engineering "for compatibility purpose" (that's > legal) would be required on those products. > > Fabio > > CalvIA IA wrote: >> >> Hi, >> >> oh, i did the listing out of sound devices, refering to the sndinfo.c >> sample. >> >> selected a different playback device from the list using >> "pjsua_set_snd_dev ();" >> >> yet the audio is still coming out from the rear speaker. >> I tested many other voip clients (Skype, Tivi, SJPhone) on WM, I wonder >> how they route it successfully to the ear speakers. > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip@lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org >

Tested. not working. It does turn on and off the speakerphone (can be noted from the icon at taskbar area) on WM6, but audio still output from the rear loudspeaker.

Hi Fabio, Can you elaborate on the reversed engineering done to route the audio output to the ear speakers? Thanks.

Simply there are several software out there that use the earpiece instead of the loudspeaker. How they do? It's a matter of reverse engineering their application a bit to understand exactly how they do, in terms of system call. It should not be so complex imho, Windows Mobile it's a quite easy platform to reverse engineer.

Hi, not many release their source codes though...
