パルスオーディオサウンドの問題

私の質問全体の基礎となる全体的な質問は、Linuxのサウンドに関するものです。 alsa、pulse、または何を使うべきですか？私は今パルスを使用していますが、私の問題は次のとおりです。 Awesomeを設定し、音楽を再生すると同時にAwesomeを再起動しましたが、サウンドが機能しなくなったことがわかりました。少しデバッグして欲求不満の終わりに再起動しましたが、音はまだ機能しません。 pulseaudioは非常に冗長なモード（ポスト下部を参照）で実行されたときに多くの出力を提供しますが、コアは次のとおりです。

D: cli-command.c: Checking for existance of '/usr/lib/pulse-0.9.21/modules/module-udev-detect.so': success
D: module-udev-detect.c: /dev/snd/controlC0 is accessible: no
D: module-udev-detect.c: /dev/snd/controlC29 is accessible: no

推測はありますか？
