Arch Linux ARM 音频不工作 (chromebook)

我目前正在从我的 Samsung Chromebook（型号 XE303C12）上的 SD 卡启动 Arch Linux ARM。我已经安装了带有 PulseAudio 和 Alsa-utils 的 XFCE4 DE。我无法让任何音频在我的安装中工作。我已经尝试使用取消静音alsamixer，但没有成功。谁能帮我解决音频问题吗？这是一些额外的信息：

一般系统信息：

[root@alarm alarm]# uname -a
Linux alarm 3.8.11-4-ARCH #1 SMP Sat Oct 22 11:59:55 MDT 2016 armv7l GNU/Linux

声卡信息：

[root@alarm alarm]# cat /proc/asound/cards
 0 [DAISYI2S98090  ]: DAISY-I2S-98090 - DAISY-I2S-98090
                  DAISY-I2S-98090

请求的journalctl输出：

Chromebook 中使用的一些音频编解码器（芯片）在最新的内核版本中受支持，而有些则根本不支持。您应该检查是否有更新的内核，因为 3.8 非常非常旧（这是使用基于 ARM 的 Chromebook 的主要缺点）。

解决方法包括使用蓝牙 A2DP 或 USB 音频适配器/声卡/DAC。
