This script can serve as a unified interface to various audio tests that we are developing. Kurt (adding in CC) has suggested to plug-in e2eaudiotest into this as well. Also, has it already been shown to work on all of the listed board? > It has been tested on Panda, imx6, Origen as of now, and the script works as expected. However, the tests obviously fail where audio recording is not supported by underlying kernel. > > On Tue, May 15, 2012 at 9:00 AM, Harsh Prateek Bora <harsh.b...@linaro.org > > wrote: > >> AudiVal (Audio Validation Suite for Linux) >> >> This is an attempt to automate and integrate various audio related tests >> which >> can help validate audio on various boards supported by Linaro.
