關於音效卡不出音發表一下意見

原創：紅旗社區lon

首先要確定您的音效卡是否已驅動

方法：lsmod|grep snd

看有沒有輸出

類似
[root@LONCHINA ~]# lsmod|grep snd
snd_intel8x0 35868 4
snd_ac97_codec 96804 1 snd_intel8x0
ac97_bus 6144 1 snd_ac97_codec
snd_seq_dummy 7812 0
snd_seq_oss 33408 0
snd_seq_midi_event 11008 1 snd_seq_oss

snd_pcm 74244 4 snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd_timer 24836 3 snd_seq,snd_pcm
snd 53252 15 snd_intel8x0,snd_ac97_codec,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore 11488 1 snd
snd_page_alloc 14088 2 snd_intel8x0,snd_pcm

要注意一個rpm包 kmod-alsa ，有的音效卡不需要這個包的，有必需這個包，以上操作沒有輸出，就要試著裝上這個包，重啟一下試試，我的音效卡就不需這個包

下面是Everest中此包的內容
