Oppo HA-2SE no longer showing up in Roon or MacOS system settings

[desbiss]

Any news on this? Do we know if it’s with Sequoia? Or does it seem related to Roon…?

I’ve got a 2023 Apple M3 MacBook Pro updated to latest version of Sequoia and just noticed today that my Oppo HA-2SE does not appear in Roon anymore. I can’t see my Oppo connected in Sequoia’s System Settings or anywhere.

I found some details online indicating others are having issues with Sequoia not recognizing USB drives, hubs etc. One of the workarounds was in “Privacy & Security” to set “Allow accessories to connect” to “Ask Every Time”.

Doing this makes the “Allow accessory to connect?” window appear (twice), but I am unable to click “Allow”…

Seems to be a Mac issue but I’m curious if anyone has been able to confirm that it has nothing to do with Roon…?

Hi @desbiss,
Thanks for writing in to ask about this. I split this into it’s own post as it is a separate case from where you posted. While another issue you see may seem related to your issue, differences in system set up and other factors mean that your case needs to be looked into separately.

@desbiss

If the audio device isn’t showing up in your Mac’s system settings then the issue is either with the Mac or your Oppo. If this was a Roon issue you would be able to see the device in system settings. Sorry we can’t be of more help.

Thanks for splitting this @daniel, apologies for my oversight. Seemed a good place to add my +1…

In my case the audio device does not show up at all in Roon, per pic below… Can you advise where in Mac “System Settings” it should appear?

With the HA-2 connected to my Mac (and powered on), I have checked “Audio MIDI Setup”, as well as “System Information > Hardware > USB”, and it’s not showing…

I am presuming this is likely a Mac issue… Everything worked prior to macOS Sequoia. There are lots of posts online about USB devices not being visible in Sequoia so hopefully they’re on it.

Hey @desbiss,

@desbiss

If the device isn’t showing up on the Mac, you’re correct in that its likely a Mac issue at the current moment.

@desbiss

Doing this makes the “Allow accessory to connect?” window appear (twice), but I am unable to click “Allow”…

What happens or what actions are your taking right before you get stuck with not being able to click ‘Allow’?

You can completely close down Roon while you troubleshoot getting the Oppo HA-2SE to become available on the Mac.

Another potential option to test - follow the same process of connecting the Oppo HA-2SE to the Mac, but this time, have your Mac settings>Privacy and Securty tab open, and have it scrolled down to the bottom of the page.

First, see if you have ‘Allow accessories to connect’ set to ‘automatically when unlocked’

Next, go through the connection process - see if a prompt pops up on the same Privacy & Security page in relation to the Oppo HA-2SE, and see if you’re able to allow it from this screen.

Hi @benjamin see responses inline below

@benjamin

What happens or what actions are your taking right before you get stuck with not being able to click ‘Allow’?

This only appears when “Privacy & Security” > “Allow accessories to connect” is set to “Ask Every Time”. The window appears, disappears, reappears, then disappears all on its own. “Allow” is blacked out and can NOT be selected.

Thank you, that has been part of the steps taken.

With the “System Settings” window open and “Privacy & Security” → “Allow accessories to connect” → “Automatically When Unlocked”… there is no prompt that pops up in regard to the Oppo HA-2SE whatsoever. Pic below with settings as suggested. I tried reconnecting the HA-2SE a few times…

The only Pop up that will appear with any of the “Allow Accessories to Connect” options, is the window that appears on it’s own, as shared prior (when set to “Ask Every Time”)

@connor flagging the other thread I mentioned. My last post is above

[benjamin]

Hey @desbiss,

Thanks for giving that a try! Have you reached out to the manufacturer directly yet? They may have additional information and steps around the recent Mac update.

@desbiss

the window that appears on it’s own, as shared prior (when set to “Ask Every Time”)

Are you able to adjust that setting to allow it automatically?

Have you tried a different cable, and port, between the Mac and Oppo device?

[desbiss]

Hi @benjamin thank you. I have since been in contact with Apple and had a remote session with a Sr Advisor. They’d noted the issue but the only solution offered was to revert to the prior Major macOS… I’m quite certain this is a Mac issue…

I have changed the settings to Automatic Connect, as well as every other option. The only one which has any indication of a connection to my HA-2 is the aforementioned “Ask Every Time” setting… All USB ports have been tried, as well as different cables…

[desbiss]

UPDATE… Hello again @benjamin. I just noticed something which may help diagnose…? See related 2 pics…

In Roon → Settings → Audio with the HA-2 connected to my Mac, and the HA-2 NOT powered on; I see the below behaviour when I turn ON the HA-2…

Initially (see first pic) there is a momentary flash of the HA-2 being connected and “Enabling” under “This Mac”. The grey HA-2 box then disappears in less than a second.

The 2nd attachment is what then remains visible… Note that all “This Mac” devices disappear, and only the “Other network devices” remain…

To make the “This Mac” devices reappear the HA-2 has to be powered off…

[connor]

Hi @desbiss,

Thank you for the report. The loss of all devices reporting under the “This Mac” tab indicates the coreaudio, the Apple sound kernel, has lost connection to Roon.

As an additional test, open the Audio Midi Setup tool again from the Applications → Utilities folder. Repeat the same test you described above:

1. With the Oppo connected and powered off, open the Audio Midi Setup tool
2. Power on the Oppo device. See if there are any visible changes to the other audio devices listed on this screen, like the Mac Speakers.

If the Oppo’s device announcement on powerup is affecting Roon’s ability to interact with the audio kernel, then we want to test if the Oppo is simply crashing coreaudio entirely.

Next, open Roon and repeat the same test so that you’re in the condition of your second screenshot above, with all local Mac-managed devices missing and only Other Network Devices available. While in this condition, open the Terminal application from the Utilities folder and enter this command exactly:

sudo killall coreaudiod

Do you see the Mac-managed audio Zones re-appear?

Lastly, what happens if you first 1) close Roon on this machine and then 2) with the Oppo already powered on, open System Settings → Sound and assign the Oppo HA-2SE as the system output?

Is Roon able to retain this Zone if it’s assigned as the MacOS System Output?

The screenshot below is what I see when following these steps. There is no change between step 1 & 2 whatsoever. The Oppo HA-2 has NOT (yet, read on) appeared at all in Audio MIDI Setup, since the install of macOS Sequoia…

Interestingly, when I tried this the grey box with the Oppo HA-2 “Enabling” would NOT appear at all in Roon, and there were no changes to the items depicted on the Audio tab… I disconnected and reconnected the HA-2 (power OFF) and there was no change to this behaviour. It was not until I reconnected the HA-2 with the Power ON, that I got the second window as was visible in my last post. 1st pic below…

When I entered “sudo killall coreaudiod” in Terminal, the Mac-managed audio Zones did NOT re-appear in ROON… but the HA-2 DID then appear in Audio MIDI Setup. See 2nd screenshot below, it has NOT yet been visible there whenever I’ve checked since having installed macOS Sequoia.

@connor

With this set (1st pic below), I can hear system sounds from my Mac through the HA-2. However… when I open Roon I am still seeing the same options in the Audio tab. See 2nd screen shot below… NO “This Mac” options appear, which is where the HA-2 should be visible. From there, power cycling the HA-2 has the same effect as prior on this tab…

Lastly… Upon disconnecting the HA-2 from the Mac it is no longer visible in either Audio MIDI Setup or System Settings → Sound when the HA-2 is powered on.

Hi @desbiss,

The real question is why the Mac audio daemon is not engaging with the Oppo when the device is plugged in. Roon’s control of this device is entirely sanctioned by the audio driver - unfortunately, everything points an issue between the Oppo firmware and this driver on Sequoia.

Oppo discontinued the The HA-2SE in 2016 and firmware updates have been deprecated.

This is sadly outside of Roon’s control. The next step would be to engage Oppo support directly: OPPO Digital - Product Support

[desbiss]

Thanks @connor and to the Roon team for digging into this. At least this rules out Roon…

I have contacted Oppo support and they acknowledged a possible issue, as they had a similar report with another DAC device. Unfortunately, given that OPPO Digital is no more, it is not likely they will be able to look further into this. With that said, their guess is it is related to macOS as the issue coincided with the update to macOS Sequoia.

Interestingly, the HA-2SE still works perfect with my iPhone which has been updated to the latest iOS. The Oppo team noted that the driver that runs the HA-2SE in an iOS device is likely different than the driver in macOS…

Truly am hoping Apple will fix this in an upcoming release of Sequia… I need to determine how to get this on their radar…

UPDATE @connor with the latest Roon update this problem seems to be resolved. Ironically, I had a call with an Apple Sr Advisor to take system logs and for some screen recording so they could submit the issue to their engineering team. However, when we commenced the call the issue seemed to have been resolved and the HA-2 is now recognized by Roon… The only factor that changed was the Roon update, so not sure if the fault was with Roon (as it didn’t appear to be per the dialogue above). Apple has the logs and has asked that I monitor for a week before they submit to their Engineering folks…

2nd UPDATE @connor I’m following up with another update which may hopefully help others experiencing USB connectivity issues in relation to macOS Sequoia…

After my last update, I realized my HA-2SE was only visible on 1 of the USB ports on my MacBook Pro. I have since been able to get my OPPO HA-2SE fully functional on each USB port. I believe the issue is in regard to an item that is flagged in the Techradar article: “PSA: macOS Sequoia is reportedly causing frustrating USB problems for some users”, linked here.

***Essentially, by leaving the HA-2SE connected and powered on overnight to my MacBook Pro (one USB port at a time), the HA-2SE eventually became visible in MacOS. I could then set it up as a new device in Roon, which seemed a bit odd to have to do for each USB Port… but it seems to be port-dependant.

NOTE: each USB port has to be ’trained’ in the same manner for macOS to eventually ’see’ the device…
