Under Vista 32 bit SP2 was working fine with old Sigmatel sound driver.
Now with last IDT driver AUD_allOS_D20001.0x_PV_IDTGUI_v105_Legacy.exe sound is distorted. With instrumental music not so bad but voice (song and speech) is compare to music very quiet and hard to understand. Windows sounds have different sonance from olds. Same for mp3, avi, wma, orig CDs, different players. Only old mono mp3s are acceptable but not origin sound.
No help now from old drivers. BIOS updated.
Any idea how to reinstall sound driver? I think there is need to manual delete some sound driver files or settings?!
Thank you in advance.
I'm no geek but I have the DP35DP and my sound is fine. I checked in "Devices" and it shows High Definition Audio Device and is running a Microsoft driver 6.1.7600.16385 date 7-13-2009.
