gnome 桌面環境的音效mixer ??

請問現在還有沒有需要裝類似audio mixer這類的東西?
我記得古早已前的linux需要 不知道現在要不要

目前我的電腦只裝alsa
但是遇到的問題是
我先開了mplayer 播放音樂
firefox 有動到flash player 會沒聲音

所以我懷疑是不是需要另外加裝audio mixer的東西


請問是這樣的問題嗎?
請問該怎麼解決
有沒有howto/wiki/toturial 可以參考的?
感恩

flash會優先使用oss發音,因此會獨佔音效裝置,解決方法之一是使用pulseaudio,不過我個人覺得裝pluseaudio很麻煩,所以沒用這個方法。我是讓mplayer的音效輸出遇到被佔住時就fallback回oss暫時解決這個問題。

經過各位大大提示之後
我大概試了一下

1. 先開firefox 播放youtube 做測試
2. mplayer 不設定參數播放mp3
的確預設為先找oss 為ao, 並說明/dev/dsp busy
改為alsa device
3. 將mplayer 開啟為 -ao alsa:noblock 模式
就不會與firefox flash player ao衝突

似乎alsa 的performance 沒oss 這麼好
另外一問,有辦法把firefox flash player 改在alsa 嗎?

是不是要裝alsa-oss? (我的gentoo 沒裝) 來偽裝成oss
裝與不裝,會牽動到哪些歷史因素嗎?
(裝了a, 就不能裝b 之類的衝突問題, 版本問題等等)

抱歉,對alsa 和oss 的歷史糾結一直都搞不清楚
請問alsa 和oss 這類的問題有沒有比較好的解決方式呢?
