电视卡图象没声音问题?
我用的是天敏电视宝贝10 Moons TV Baby（BT878）,在windows下工作正常，在MLlinux下用kdetv,tvtime和xawtv都能看到清晰的图象，但就是没有声音在MLlinux下单独播放声音正常，可播放MP3
反复检测Mixer的line in也是打开了的
我的声卡是:SIS 7012
etc/modprobe.conf是这样

不知那位高手能给指点一下，或是给点思路也可 不仅仅是Line In，看看 Aux In 打开了没有。 Mixer的所有选项都是打开了的 我的打开Line和IEC958就有声音了，但声音会有杂音，图像也没有Windows下好，且调到的台不完整。 请问IEC958是什么呀?
我在linux下看图象效果很好,但也有几个台调不到的毛病. 我的打开Line和IEC958就有声音了，但声音会有杂音，图像也没有Windows下好，且调到的台不完整。
多尝试关闭和打开一些东西，如果听MP3没有杂音，这个也不应该有的。 alsa 作为一个通用的声卡解决方案，效果和自动化程度肯定比不上 win 下的商业驱动。你需要自己尝试调整设置。 在我的电脑里，只要打开IEC958就会有杂音(其它能关的都关闭了),听MP3时也会有杂音，关闭了就正常了，但电视就没声音了。
我的声卡：Create pci 128 声音小应该是设置的问题吧？和驱动关系不会很大，这主要取决于你的声卡的输出能力，也就是它的内部运放电路。 终于解决了，在10moons论坛上找到了答案
天敏的TV Baby应该在modprobe.conf中这样设置
options bttv card=54 audiomux=0tuner=37
如果card=54设得不对，就会有些台收不到 有人知道tvmaster2遇见同样的问题怎样解决吗?
我的所有开关都打开了的,音箱也是直接接在电视卡上的!
图象很清晰,但是没声音!
