USB DAC crashes when phone is locked #1631

try setting usb accessories to "allow new USB peripherals" in settings > security > usb accessories |
|
Actually tried before creating this ticket, the behavior is the same |
|
I can provide a DAC or fund a purchase of one for whoever will be working on this issue |
|
Maybe try the ANKER DAC. It works without problems for me on Pixel 6a. |
|
Need to know if anyone can replicate the issue on a Pixel 4 or Pixel 5. |
@thestinger I can confirm that the issue does not happen (at least the music stopping when phone is locked) on my Pixel 4 that is also running grapheneOS. Is there anything I can do to help resolve this issue? |
|
it seems like I can't replicate this issue on Pixel 7 with Apple Type-C to 3.5 dongle |
|
The initial post says that it's occurring for them with a Pixel 7 Pro. Maybe it only happens with certain kinds of DACs. |
|
@maade69 will respond to this comment here to centralize all discussion about this issue these are the earphones I have. Nothing special. |
|
Same for me with Pixel 6. I used my USB-C audio converter (https://www.jsaux.com/products/jsaux-usb-c-to-3-5mm-cable-adapter) successfully back in September, that's all I can say on when it worked the last time for me (don't really use it often). Maybe I was still on Android 12 back then. |
|
@F1VWdk i am unable to reproduce the issue with BTR5 on pixel 7. |
|
Experiencing the same issue on a Pixel 6 Pro. Was working just fine a week or so ago. USB accessories is set to Allow new USB peripherals. I have two Google USB C to 3.5 adapters. One I had never used before but the issue is the same on both. |
|
@shape-err I am unable to reproduce this bug with Google USB-C to 3.5 mm Adaptor and Pixel 6 pro. How i can reproduce this bug (step by step) and on what build number (settings > about > build number)? |
|
@empratyush
|
I am sorry but still unable to reproduce this issue . |
|
for me, I have a Google Pixel 6 with Build Number 221105.002.2022111800 and my steps to reproduce is:
To get the song to start playing again, I have to
|
|
I found the problem, default USB settings were set to File Transfer. |
|
I can confirm that @shape-err 's "fix" does work on my Pixel 6 too. |
|
Confirmed. Works for me too, Pixel 6. |
|
Are you using a Pixel 6 (not PRO)/

@empratyush wait, is this expected behavior? cause this was not how the phones used to work. |
|
@empratyush I always had "Data transfer" as default setting for USB. It used to work before as mentioned by @b3K1ndRw1nd |
|
@psz1234 Yes, Pixel 6 (not Pro) |
yes, by default "Default USB Configuration " is set to "No data transfer" for privacy/security reasons. |
|
You shouldn't need to change anything in developer options. The developer options USB transfer mode is a different thing than the user facing one. Does this work for you with developer options disabled completely? |
|
I don't think this issue is resolved. I think people are messing with developer options in a way that they shouldn't be. OS level file transfer enabling is not the same as that. |
For me it works as expected with developer options disabled completely (Pixel 6). That means music playback doesn't stop when the screen is turned off. |
@thestinger Not sure if I am misunderstanding you or you are legit saying that users should not be enabling USB file sharing on their pixels? |
I think changing the default behaviour of USB by setting developer options is messing this up. |
|
If everyone here previously changed the developer options setting for this, then that's the issue. Developer options are for testing and aren't intended to be used this way. |
Accepted |
@thestinger is there another option for doing a USB file transfer to and from a Pixel phone? |
|
It's in the standard USB menu in Settings -> Connected devices. There's no reason to use developer options for this and it's broken. When you connect a USB device, a notification is shown with a shortcut to the USB settings menu in Settings. |
|
I see. well I weekly use the |
|
You don't have to do that. ADB doesn't cause any issues with this. |

Thank you everyone for troubleshooting this and finding a .... I wouldnt call it a solution but a workaround. Never in the past me changing "Default USB Configuration" in Developer options caused any issues - not with USB operations, not with external DAC and music - and that is way I always changed USB to "File Transfer".
I disagree with @thestinger about the use of this and other developer options: on stock android it does not cause any issues and makes my use of the device more convenient - I dont see any reason why I shouldnt use it. There is definitely something different on GraphoneOS from stock as selecting "File transfer" in "Default USB Configuration" of Developer options causes an issue that is not present on stock - it's a fact. Whether devs decide if it's worth or not to look into this - that's another matter. I'll change "Default USB Configuration" to "No file transfer" but it's a workaround, not a solution. |

You're wrong. It works the same way on the stock OS based on the same version of AOSP. It's also not an opinion that developer options are intended for developers and not production use. There are a whole bunch of broken ones, ones with major unexplained caveats and ones that don't do anything. Features are in developer options because they're only useful for developers, extremely dangerous (ADB) or too half baked / broken to be exposed as regular options for users. Please don't unnecessarily bump issues and do research before trying to contradict things stated by the GrapheneOS team. You could confirm for yourself this occurs on stock OS. |
Aside from not being implemented properly in a way that doesn't break things, I think the reason they haven't done that and added it as a normal option is fairly obvious: even using the regular approach that needs to be enabled each time is a quite insecure approach to file transfer where the attached computer gets access to the user's whole home directory. Having that happen automatically without the user unlocking and enabling it is a pretty big issue... |
Observed on Pixel 7 Pro and 6
Pixel 7 Pro Version: [TD1A.220804.031.2022102800]
No additional drivers/software installed for the DAC
Spotify plays Ok while phone is unlock or locked when output to Bluetooth headset
with USB DAC:
while phone is unlocked, connect USB DAC (BTR5 by FiiO)
start Spotify, it plays ok to USB DAC while phone is unlocked
the second phone is locked, sound stops. Unlocking phone causes Spotify to crash without restoring sound. Once started again, Spotify plays fine to the DAC while phone is unlocked, locking phone repeats the cycle.
Observed similar behavior using Amazon Music but unlike Spotify, AM did not crash after unlocking the phone but instead reported "exception 800" and needed to be forced closed and restarted to resume play.
This playback configuration was working on the the same phone with Android 13 (and 12)
