There was a problem importing one of the Python modules

required to run yum. The error leading to this problem was:

/usr/lib64/python2.7/site-packages/pycurl.so: undefined symbol: CRYPTO_num_locks

Please install a package which provides this module, or

verify that the module is installed correctly.

It's possible that the above module doesn't match the

current version of Python, which is:

2.7.5 (default, Oct 30 2018, 23:45:53)

[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)]

If you cannot solve this problem yourself, please go to

the yum faq at:

http://yum.baseurl.org/wiki/Faq

[root@localhost ~]# cd /hrifs/usr/lib/

[root@localhost lib]# rm -rf libcurl.so libcurl.so.4

[root@localhost lib]# yum install alsa-utils -y

声卡的杂音来自于电磁信号；

声卡出现杂音的原因很多，但通常情况下，是由于输入接口的针脚感应引起的；

解决方法1，在音量控制中心，将线路输入、CD输入等没有接入输入设备的接口设置为静音；

解决方法2,短路没有使用的输入接口；

无论是集成或独立声卡，都不会出现接地不良的情况；
