Normally-working code crashes with: signal 11 (SIGSEGV), code 2 (SEGV_ACCERR) (AudioRecord) #1571
Description
Hi, I am new to Oboe but am working on a cross-platform audio app which uses it for the Android version.
I just bought a (relatively) new Android phone for testing, and was surprised to see that Oboe seems to have some issue with it. (This app is working fine on a variety of other phones.)
For reference, the Android-specific code for the app is maintained here. Please let me know if I need to supply more details, thanks!
Android version(s): 11 -- UPDATE: Actually version 12
Android device(s): Xiaomi Redmi Note 10 Pro
Oboe version: 1.6.2
App name used for testing: koord-rt
Short description
When an audio stream is opened for recording, the app exits suddenly with:
F libc : Fatal signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 0x7c45df2000 in tid 20486 (AudioRecord), pid 20231 (e.koord.koordrt)
See below for more debug logs.
Steps to reproduce
- connect to a live session, which opens device for recording
Expected behavior
- audio stream is opened without problem
Actual behavior
- app crashes - exits without message
Device
Xiaomi Redmi Note 10 Pro
