Arch Linux ARMオーディオが機能しない（Chromebook）

現在、Samsung Chromebook（モデルXE303C12）のSDカードからArch Linux ARMを起動しています。 PulseAudioとAlsa-utilsでXFCE4 DEをインストールしました。インストール時にオーディオが機能しません。私はalsamixer成功せずにミュート解除を試してみました。オーディオの問題に役立つ人はいますか？以下は、いくつかの追加情報です。

一般的なシステム情報：

[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

[root@alarm alarm]# cat /proc/asound/cards
