+Subject: [PATCH] (halium11) libaudioclient: Fix infinite loop in get_audio_flinger()
+
+Problem:
+In Halium environments, AudioFlinger is replaced by CameraRecordService
+for audio recording.
+However, get_audio_flinger() still attempts to contact AudioFlinger
+using an infinite blocking loop:
+
+    do {
+        binder = sm->getService(String16("media.audio_flinger"));
+        if (binder != 0)
+            break;
+        ALOGW("AudioFlinger not published, waiting...");
+        usleep(500000);
+    } while (true);
+
+When AudioFlinger is not started, getService() never succeeds,
+and the function remains trapped in the infinite while(true=) loop,
+blocking the audio thread indefinitely.
+
+Impact:
+Camera video recording with audio in hardware mode might fail
+on halium-11 for some devices.
+
+Solution:
+Check for CameraRecordService. If running, skip audioflinger wait loop.
+
+- Tested on Xiaomi POCO X3 Pro (vayu) running Droidian-101/Halium-11.
+- Camera app: new droidian-camera from 102 (qt6 hybris-compat)
+  https://github.com/droidian/droidian-camera/tree/feature/next/hybris-compat
+- Camera video recording with audio in hw mode now works.
