# 1. 检查延迟加载
systemctl status audio-delayed-load.service

# 2. 验证 model 参数
cat /sys/module/snd_hda_intel/parameters/model
# 应输出：laptop-amic,(null),(null),...

# 3. 检查音频设备
aplay -l
# 应能看到 SN6140 Analog

# 4. 查看 codec 信息
cat /proc/asound/card*/codec* | grep "Codec:"
# 应输出：
# Codec: ATI R6xx HDMI
# Codec: Conexant SN6140

# 5. 查看内核日志（不应有 "no codecs found" 错误）
sudo dmesg | grep -i "hda\|codec" | grep -i "error\|fail"
