Glitch detected on Fidelity Test RRS feed

  • 问题

  • 我在Montevina平台上测试“Fidelity Test - Mobile (System,Manual)”和“HDAudio Class Driver Fidelity Test - Mobile
     (System, Manual) ”两项测试时频繁遇到这个问题:

    Glitch detected; this test case will fail. Look into possible sources of glitching;

    For example, network card drivers or video card drivers; unduo load, etc. Will

    retry and continue test case anyway.

     

    其中Fidelity Test是fail在“Input Level Test”和“Capture Frequency/Magnitude Response Test”这两个子项

    HDAudio Class Driver Fidelity Test 是fail在“Input Level Test”这一项。

    有时又能PASS,但PASS的几率非常低。

     

    想请教一下大家,这个问题怎么处理?

答案

  • a. make sure the system connect to the ground correctly.

    b. when the test asks for plugin in put cable, pls keep the line out cable in the system.
    1. AP ask for speaker/lineout test, plug in AP cable to Speaker/headphone, etc;
    2 after Output test completed, it asks for Input test, pls plug in another Ap cable to Mic-in; do not unplug the AP cable in step1. 
    this might remove the glitch detected failure.

  • 我也遇到过和你一样的情况,最后是跑了很多很多次才pass的,反正只要一次通过就可以了。
