        This option enables Bluetooth Audio support. The specific
        features that are available may depend on other features
        that have been enabled in the stack, such as Periodic
        Advertisement for Broadcast and L2CAP Dynamic Channel
        for Unicast.

config BT_AUDIO_BSS_SEG_EXTERNAL_MEMORY
    bool "Place BLE Audio .bss segment in external SPIRAM"
    depends on BT_ISO_BSS_SEG_EXTERNAL_MEMORY
    default n
    help
        Place the zero-initialized (.bss) static data of the BLE Audio
        profiles in external SPIRAM instead of internal DRAM. Covers both the
        esp_ble_audio IDF source files and the .bss of the prebuilt BLE Audio
        library (libble_audio.a), the latter relocated via a linker fragment.

        Depends on BT_ISO_BSS_SEG_EXTERNAL_MEMORY: the audio layer sits on top
        of the ISO/host layer, so its static data is moved to SPIRAM only when
        the ISO layer's is, keeping the placement coherent.

        Requires SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY. Only .bss is moved;
        initialized (.data) statistics stay internal.

config BT_AUDIO_HEAP_EXTERNAL_MEMORY
    bool "Place BLE Audio heap allocations in external SPIRAM"
    depends on BT_ISO_HEAP_EXTERNAL_MEMORY
    default n
    help
        Route BLE Audio runtime heap allocations to external SPIRAM instead of
        internal DRAM. Covers both the esp_ble_audio profiles and the prebuilt
        BLE Audio library (libble_audio.a): both allocate via idf_ext_calloc /
        idf_ext_malloc, which this switch points at the ISO layer's SPIRAM
        helper (heap_caps_*(MALLOC_CAP_SPIRAM)).

        Depends on BT_ISO_HEAP_EXTERNAL_MEMORY: the audio allocator hook reuses
        the ISO layer's helper, available only when the ISO layer routes to
        SPIRAM too.

        On SPIRAM exhaustion allocations return NULL (no internal fallback).

        Note: this option does NOT affect logs from the BLE Audio IDF
        source files (esp_ble_audio component, "LEA_*" tags) - those
        are controlled by BT_ISO_NO_LOG / BT_ISO_LOG_LEVEL under the
        "BLE ISO Options" menu.
