Red light from headphone jack mac no sound

Re: S/PDIF Digital Output: How to turn red light in headphone jack off on Macbook Pro

I will change the wiki eventually. So the second suggestion with using both cards in the same options line is correct. It does change the order, depending on the vid and pid. Also simply using 'id' would be sufficient, but that brings other problems with it. Do you happen to know where the source code for parsing modprobe. Modprobe is part of kmod, but I did not have time to search intensively.

Edit: I put a hold on that. Dmesg still throws ignore warnings, yes I am aware of that particular modules parameters. I thought snd took over here, apparently not, so this may have to do with slots. I didn't say use it with both cards.

A single option. I've been trying to figure out why that works, and this is what I've come up with: The first initialized audio device will get index 0 and thus be default. Yes, only thing is, this is pretty unreliable should the default card become something else than default.

  5. I can read, thank you. How about you? It has been an unfortunate coincidence in my case, since I tested this on two separate machines, but apparently missed the dmesg, used it with a different hardware setup back then or already aliases came into place.

    Since it worked, I left it at that, I should have known better. I would argue the behaviour is that of slots, since like I already mentioned the enable parameter behaves very similar in appropriate circumstances. But it is inconsistent, or so it seems, which is the reason I need to go through the source code. But that's just the thing, it doesn't get specified to the wrong card.

    Maybe that's coincidence, but I think it's more than that. I've been thinking it has to do with pci bus order. Actually, that won't work. The id option doesn't select, it assigns. I fully understand your train of thought and it is a good one. But again, should the default cease to be default for whatever cause the whole concept falls apart, which is the reason I have been, wrongly apparently, pushing vid and pid, since this would limit incorrect behaviour to a very few exceptions, like exact same hardware in unfortunate hardware paths and therefore order, so highly improbable.

    Yes, I see less inconsistencies with the boot order as compared to few years back. Maybe it comes with new hardware. I would argue, that there are just too many hardware configurations to settle with one ambiguous approach however, that might exclude a whole group of users. Maybe I am overcautious here.

    I wish the documentation would have been more precise at this spot.

    I will scratch that previous part, but it would have been so much easier if it worked the way I interpreted it would. Good thing you pointed that out, I appreciate it. It looks like slot behaviour - first argument of a parameter goes to the first card, here A. Both A and B use the same module. Saser should you use the approach Gusar pointed out, do remember about it next time you have audio problems. Maybe it is the better approach for now, I hope the whole exchange between Gusar and me does not confuse you too much.

    I have the same machine, only issues I have are webcam and microphone related. Not much we can do about the webcam, but did you manage to get the microphone to work? I'm using PulseAudio btw.

Re: Red light from headphone jack in MacBook Pro 11,1 The 'speaker-test -c 2' probably does not work, because the default sound card has the default device other than 0, in case of HDMI it is usually 3. Wiki wrote: Also, if you are using PulseAudio, sometimes it thinks HDMI is the default sound card; to solve this problem, install pavucontrol and set Analog Stereo as the fallback device.

    If your volume controls are grayed out or you see a red light from your headphone jack, insert and remove an Apple headphone plug a few times. This has been known to fix the issue and restore sound. You'll need to have your Mac serviced to get this problem fixed for good. Some users have reported better success by using Apple brand headphones or earbuds for this procedure. Download any available updates. Click the Apple menu and select "Software Update" to begin looking for and installing any available updates. Open the Activity Monitor and stop the "coreaudiod" process.

    This will restart the sound controller for the Mac: [2] Open Activity Monitor from the Utilities folder. Find the "coreaudiod" process in the list. Click the "Process Name" header to sort the list alphabetically. Click the the "Quit Process" button. After confirming, coreaudiod will be closed and will restart automatically.

    Ensure you don't have headphones plugged in. If you have headphones plugged in, you won't be able to hear sound from the speakers. Sometimes inserting and removing a headphone plug will get the speakers to switch back on. Click the Apple menu and select System Preferences.

    If you have multiple audio devices connected to your Mac, it may not switch inputs correctly.

    Click the "Sounds" option and then select the "Output" tab. This will display a list of devices that can output audio. Select the proper output device. Select the device that you want to use to play sound. Check the volume level of external speakers. Many external speakers will have their own volume controls.
