Found a new problem, although the sound has a problem with the sound preemption, one program calls the sound information, the other is not available. Very annoying, query a bit, the current method can be resolved:
First: sudo apt-get install libesd-alsa0
Second: sudo gedit/etc/asound.conf (new)
Fill in:

In the ubuntu14.04 version of the server installed desktop, browser and so on all the normal use of video playback, found no sound, downloaded SMPlayer video player found no sound, speculated that the sound card driver problem, was tortured for two days, the following is the solution.
1. System: ubuntu14.04 Server version
2. Question: No sound, whether in a browser, video player or spicy client link instance
There's no sound in the video that's playing inside.
3. Solution:
Alsa+pauseaudio
2.6.x version of the kernel also contains OSS, they have been officially replaced by ALSA.
ALSA-Advanced Linux Sound Architecture (alsa,http://www.alsa-project.org) is an alternative to OSS. ALSA is both compatible with OSS and provides a new approach to audio interface. ALSA, as a standard for the 2.6.x kernel, can also be compiled into modules used in the previous kernel.
Esound-esound is a library and background service designed to provide a unified interface for Linux audio systems, wheth
With the improvement of computer performance and the increasing traffic, traditional local area networks are getting more and more out of their load. The exchange Ethernet technology has emerged, greatly improving the performance of local area networks.
A network switch can significantly increase the bandwidth and establish a geographically dispersed network. Each port of a LAN switch can transmit information in parallel, securely, and in real time. It features stable performance, flexible struc
The install. wim file is not installed on the WIN8 hard disk. The solution is as follows: the official win8 version is not installed on the hard disk like Windows 7, because the install. wim file is not in ISO, but the install. esd file. Is installation inconvenient? Www.2cto.com solution: 1) enter the PE, format the C drive, and copy the boot folder, sources folder, efi folder, and bootmgr in the WIN8 directory to the C drive root directory. Then exi
. Some buttons also add a shadow paper between the keycap component and the bracket to prevent transmission between the buttons.
The bracket material is determined based on the button thickness. It can be injection molded with PC or ABS, with a thickness ranging from 0.8 to 2.0mm. Alternatively, it can be directly punched out with PC sheet with a thickness of 0.5, 0.6 or 0.7mm; when the button thickness is not enough, the bracket material is made of 15mm mm thick stainless steel, but considering
If you do not have a Sybase ASE server or client environment at hand, you can consider using this Internet-based ASE test server when you want to view commands or parameters that are not accessible to the ASE server.
This blog is for beginners or DBAs of Sybase.Completely freeThis ase15.0.3 test server is provided. The server where ASE is located is the U.S. VPs virtual machine purchased by the blogger at his own expense.
Currently, the ASE test server only supports PHP page access. The direct

can directly decode these 5B code groups, and 00100 generates the signal rx_er. When sending, You need to determine the signal bit sent from the MII interface: If tx_en is on the rising edge, the SSD will be encoded when the first two leading codes are on. If tx_en is on the falling edge (frame interval ), the ESD is output after the FCS, and the code is always filled with 11111 for the data stream interval. If tx_er is triggered, the Code 00100 is o
-time performance. Therefore, the topology structure and communication protocol of the physical bus are particularly critical.
2 Interface DesignGood interface design should ensure good anti-interference, stability and scalability of the system on the hardware. This system selects a half-duplex interface chip sn65hvd3082 with high cost performance. It has the following features:① Meet or exceed the requirements of TIA/EIA-485A standards;② Low static current consumption-the effective mode is less
