① ALSA 正确用法（核心）：不再写 /usr/data/alsa.conf（HiBy 播放器数据文件、语法非法、
libasound 从不加载，改它对解析零影响）。改为 snd_pcm_open("bluealsa:DEV=<mac>,
PROFILE=a2dp,CODEC=<token>")，参数名严格取 /etc/alsa/conf.d/20-bluealsa.conf 的
pcm.bluealsa @args[DEV PROFILE CODEC VOL SOFTVOL DELAY SRV]（实测未知参数会被
alsa-lib 拒绝）；删掉 bt_apply_device_conf/bt_apply_codec_conf 两条改写分支。
② 硬 bug：bt_dev_detect_mac() 旧逻辑取端点 token「最后一个 '/' 之后」——真机
bluealsa-cli list-pcms 输出是 D-Bus 路径 /org/bluealsa/hci0/dev_33_DE_2E_21_AD_30/
a2dpsrc/source，旧代码会把 "source" 当 MAC（旧单测喂的是人造输入所以一直是绿的）。
改按 dev_XX_XX_XX_XX_XX_XX 段解析，兼容老式 a2dpsrc/<MAC>。
③ codec：settings bt.codec 经 bt_dev_codec_token() 归一成 bluealsa canonical 名
（v4.1.1 a2dp-codecs.c 别名表，strcasecmp）；auto/未知 → unchanged（不干预协商）。
④ 失败必回落（硬验收）：新增 BT_ST_IDLE/OK/FAIL 状态机 —— 无端点/未连接/set_params
失败/写路径致命错（ENODEV 等）都回落 DAC 继续出声，绝不整机静音；回落前同步武装
numid=9（hbc3000 未烧+enable 开 PCM 会楔死整机）；STATE 增 bt=/btdev=/btcodec=
三键供面板显示「输出=蓝牙(失败)」，volctl 回落时报 dac。
⑤ 防重试风暴：只在开流/重配边界重试，指数退避 2s→60s（bt_dev_should_try），写循环内
绝不重试；用户显式切目标才清退避。
⑥ 音量：BT 真走 A2DP 时仍不下发 DAC 反转（回归确认），回落 DAC 时按 DAC 音量控；
AVRCP 一键置最大从 100 改 127（bluealsa-cli volume 满量程 [0,127]，旧值只到 79%）。
⑦ build_audiod.sh：ROOT/REPO 自动推导，ZIG/CC/LIBBT/ASOUND_SRC 可环境变量覆盖（旧
hiby_os_crack 路径在多数 checkout 里不存在），宿主链接 -l:libasound.so.2 失败退
-lasound；保留 M43 的 meow_audio time32 cli 目标。
宿主：test_bt_dev 51/51（真机 D-Bus 路径格式/别名表/退避），test_audiod_host 109/0，
0 warning。真机：新二进制 glibc-dynamic 上机正常，DAC 出声回归通过，无端点回落 DAC
出声（played/rms 实证），/usr/data/alsa.conf 全流程零写入；耳机出声一项待耳机上电。
不提交二进制、不改 fw_content.conf 钉值（按塔交付形态政策，由 M51 统一重编）。
