    Hello, I have some problem with my Alienware. When I boot laptop on battery without AC adapter plugged in there are no audio device detected and naturally there are no sound. I need to just plug in AC adapter and restart or sleep/unsleep and it works again. What is wrong? I reinstalled Sound Blaster Recon3Di drivers and reainstalled BIOS and no effect.

    Hi, I don't have an answer, exactly, but my R4 did the same for quite a while. I found that running the audio troubleshooter would fix it as well. I tried a bunch of stuff and eventually gave up. It's just an extra min or two at startup so I just put up with it.

    Then I had an SSD failure. Dell attended and replaced the SSD. Following a reinstall of windows and restoring my data the audio prob was gone!?

    I wouldn't recommend the pain of a full reinstall but that is what fixed mine..

    Good luck.

    But I had this problem long ago, even on Windows 7 and beginning of Windows 10, but it was rare and generally reboot (on battery) fixed it. Now from a few days, there are no way to fix it without AC adapter :(

    So, even the audio troubleshooter does not work for you? Sorry man, it sounds like some sort of borderline HW timing issue when on battery. Mine might have even got fixed by the strip down the tech did? The panel and KB were replaced at the same time.

    Open the control panel under "Sound" and check that your laptop's sound card is enabled and is set as the default playback device. Do this when running on the battery. There may be a driver update for your sound card or some power management feature that can be disabled and you may also want to update your video card's drivers as there may also be a conflict with your video card's audio drivers that are used for HDMI output.

    Maybe this will help too:

    When laptop goes sleep and unsleep on battery and I'm in sound settings (there where I can choose default playback device) all SBRecon3Di devices (speakers,digital output) just disappear after few seconds. Sound card also disappear from device manager. Sometimes (1 start of about 20) it works on battery until next restart/sleep. I cant use troubleshooter for this cause this device just doesnt exist in system. What is wrong :( ?
