Low volume sound from speakers (Windows 7 x64 + Cirrus Logic CS4206A [AB75] sound chip) RRS feed

  • Question

  • I am running the retail version of Windows 7 x64 and I am quite disappointed with the sound quality coming from the computer speakers (recently purchased 15.4'' unibody MacBook Pro).

    The sound chipset is Cirrus Logic CS4206A (AB75) and the driver version (which is WHQL compliant)  is 6.6001.1.8 (29/04/2009).

    The issues are:

    1.) the sound that comes out of the speakers is not very strong at all (low volume) and it is also not very high quality.
    2.) the headset port emits a red flash whenever sound is played back by the system (it will shut off after a period of no sound being played... including system sounds). 

    Can I find a newer and more compatible driver?

  • Are you using Boot Camp for your Win 7 installation?  If so, you may need to wait for Apple to publish the next version of Boot Camp which addresses Windows 7 compatibility.

    About Boot Camp and Windows 7


    Summary

    Apple will support Microsoft Windows 7 (Home Premium, Professional, and Ultimate) with Boot Camp in Mac OS X Snow Leopard before the end of the year. This support will require a software update to Boot Camp.

  • I am using Bootcamp 3.0, but given that this problem also afflicts Windows XP and Windows Vista (especially Vista because for XP there seems to be some kind of workaround available) I am a bit upset about having to wait for yet another Bootcamp update.

  • I had the same issue with my CS4206A and I downloaded another driver from Cirrus website for a CS4207 and it works! :)

  • Personally I found that adjusting the Playback Enhancements made all the difference for me.  I had the latest drivers with Boot Camp 3.3.  Info here: http://coad.cc/Npn6wd

  • Are you running Apple Boot Camp?  If so, you must contact Apple about the problem since they are the publisher of the Boot Camp software and provide 100% of the support for Boot Camp.

    Also, read your other post on the exact same thing @ http://social.technet.microsoft.com/Forums/en-US/4edb21da-51a6-4857-8acb-7ebcf8380538/low-volume-sound-from-speakers-windows-7-x64-cirrus-logic-cs4206a-ab75-sound-chip

    This is neither a Microsoft problem nor a Windows problem.  The problem is there is no support provided by the manufacturer for this device.

    I would also suggest you to contact the manufacture of the product and check @ http://www.cirrus.com/en/support/

    According to their website @ http://www.cirrus.com/en/support/drivers/ there are no Windows 7 drivers for your Cirrus device and Microsoft does not write the drivers for third party hardware.

  • This was the most helpful answer to me.  No new drivers will be forthcoming for this chipset, so tweaking the existing sound output is the best option.
