我用的是fc2系统(kernel2.6.7),alsa驱动能正确识别我的cm8738声卡,应用程序也能正确打开设备,可声卡就是不出声。请问我该怎么办.. //oss驱动能使声卡正常工作,但2.6版本的核心正在试图减少oss的影响力。
现今,见到的比较多的ethernet frames有如下的四种: a. Ethernet II b. Ethernet 802.3 (Raw), aka Novell Ethernet c. Ethernet 802.3/802.2 by IEEE d. Ethernet SNAP ---------------------------------------------------------------------------------| Preamble | Dest MAC | Src MAC | Length/EtherType | Data | FCS |--------------------------------------------------------------------------...

我现在在fedora core 3系统上安装了alsa声卡驱动,都调试完毕了。 不知道何原因设备/dev,中总是缺少声卡相应的设备。我在播放音乐是总要进入alsa-driver目录下执行./snddevices命令后才能正常启动。不知道如何设置才能自动启动相应的设备阿。 我现在这里谢过了阿
Inverse Arp Request When encapsulating other protocols the data field of the frame Relay packet contains a Network Level Protocol Identification (NLPID) which can be 0xCC (IP), 0x80 (Sub-Network Access Protocol - SNAP) or 0x81 (OSI). When a SNAP header is identified, the 3-byte Organisational Unique Identifier (OUI) and the 2-byte Protocol Identifier (PID) further identifies the protocol. ...
