External Speakers and Monterey

[lapk]

I experience the same problems

-What makes it weird is that it may work sometimes (when it does the sound goes briefly to DP or hdmi before jack output)

-My unifying dongle is also affected (sometime not recognized)

-I have another Usbc dock (small) wich is working fine every time to output sound or unifying

Im still investigating, it is really weird, maybe it has to do with the fact that D6000 has only usb3

Same issue here. MacBook pro 2020 (4 ports).

When I reboot with my dock (StarTech) connected audio is fine.

Any more info on this issue? Its a pain as I use headphones for calls and I have to plug them into the laptop directly which is further away.

I've been having a similar problem.

I have a MacBook Pro (16-inch, 2019) running Monterey version 12.0.1
and this docking station https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1.

I've been restarting the app where I experience the audio problem, and that's been working for me as a quick fix.

I just installed the DisplayLink Manager 1.5.0 and am curious to see if that makes a difference.

FYI - I don't normally shutdown or restart my MacBook. I just close the lid, and let it sleep (I suppose, like most people).

Same problem here. Sound works through "Dell USB Audio" upon restart, but after sleeping then logging back in it no longer works.

MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports)
macOS Monterey 12.0.1

D6000
DisplayLink Manager 1.6.0 Beta

Same, only restart fixes it for me. 2020 mbp with Dell d3100.

Seems to be related to unplugging the dock between restarts.

Fairly reliable if the laptop doesn't move from my desk.

Since my last post, I've upgraded to Monterey 12.2.1. Somewhere between this version and Monterey 12.0.1, my touch bar would be unresponsive when I tried to wake my MacBook from sleep. From there, I'd have to restart my device to get things back to normal.

I've found that if I first disconnect the DisplayLink before waking up the MacBook, then connect the DisplayLink after the system is up, things work as expected - including the audio.

Using a Prokord USB-C dock for my screens and other peripherals. Using MBP M1 Pro, running macOS 12.6.5.

I've experienced similar problems as described here. Sound randomly stops working and I hear a "click" from the speaker, like if you turned something off.

I've tried suggestions in this thread with some success, but nothing that works in the long term.

Other workaround that have worked?

1. Unplug the speaker cable from the Prokord and then pluging it back in. "Click" and it works.

2. Switching to another application, like Quicktime, and playing a sound. "Click" and the sound is back on again. Other times I have to start playing a video on Youtube in Chrome.
"Click" and the sound is back again.


I've also streamed system logs for a while in order to "catch" something just after the dreaded "Click" that signals sound loss, as well as the "Click" that signifies that the sound is back. This is what I got.


Here is stopped working:

default	08:35:00.514719+0200	coreaudiod	 HALS_IOContext_Legacy_Impl::IOThreadEntry: 516 AppleUSBAudioEngine:DisplayLink:DL-Dock:ZG69360100661:3 (AppleUSBAudioEngine:DisplayLink:DL-Dock:ZG69360100661:3): stopping with error 0

Here I used the other software trick in order to get the sound to work again:

default	08:35:09.085500+0200	coreaudiod	 HALS_IOContext_Legacy_Impl::IOThreadEntry: 465 AppleUSBAudioEngine:DisplayLink:DL-Dock:ZG69360100661:3 (AppleUSBAudioEngine:DisplayLink:DL-Dock:ZG69360100661:3): starting

Here is what I presume is coreaudiod reporting something after restarting the dock:

default	08:35:09.091690+0200	coreaudiod	     CAReportingClient.mm:508   message {
    "device_is_aggregate" = 0;
    "input_num_tap_streams" = 0;
    "input_scalar_volume" = "1.000000";
    "io_buffer_size" = 256;
    message = StartHardware;
    "output_avail_phys_formats" = "{ [16/48000/2 lpcm], [16/48000/6 lpcm], [16/48000/2 lpcm], [16/48000/6 lpcm] }";
    "output_avail_virt_formats" = "{ [32/48000/2 lpcm], [32/48000/6 lpcm], [16/48000/2 lpcm], [16/48000/6 lpcm] }";
    "output_bits_per_channel" = 32;
    "output_bytes_per_frame" = 8;
    "output_bytes_per_packet" = 8;
    "output_channels_per_frame" = 2;
    "output_device_source_list" = Unknown;
    "output_device_transport_list" = USB;
    "output_device_uid_list" = "AppleUSBAudioEngine:DisplayLink:DL-Dock:ZG1:3";
    "output_format_id" = lpcm;
    "output_frames_per_packet" = 1;
    "output_num_tap_streams" = 0;
    "output_scalar_volume" = "1.000000";
    "sample_rate" = 48000;

It would be REALLY nice if DisplayLink got together with Apple and solved this.

If you have not done so already, I would suggest reporting the issue to DisplayLink by following the process outlined here --> https://support.displaylink.com/know...to-displaylink
