question
raspberry-pi
Raspberry Pi で espeak を実行すると ALSA がエラーを出す
[ALSA](http://gihyo.jp/admin/serial/01/ubuntu-recipe/0177)
関連のエラーが出ているので、おそらくサウンドデバイスが上手く認識されていないのだと思います。以下のことをお確かめください。

  * スピーカーがちゃんと物理的に接続されているか。
  * ALSA などのソフトウェアからスピーカーが認識されているか。たとえば `aplay -l` を実行すると、認識されているデバイスの一覧を見ることができます。
  * デフォルトの再生デバイスがそのスピーカーになっているか。なっていない場合、`~/.asoundrc` というファイルを弄るなどして対応することになります。
