Hello,

Can any one suggest how can i test audio in am335x. Audio is detected in /dev as snd driver.D

Done as in http://processors.wiki.ti.com/index.php/AM335x_Audio_Driver%27s_Guide#Introduction

    Rajeev,

    You can try audio playback using aplay utility and record using arecord.

    Are you using the Sitara EZSDK? If so and you do not have the ability to record and do not have any existing sound files to playback you can use:

    gst-launch audiotestsrc ! alsasink

    The following TI sample file available from the Linux EZSDK works fine for me (using the headphone out plug to hear audio):

     root@am335x-evm:/usr/share/ti/audio# gst-launch-0.10 filesrc location=/usr/share /ti/audio/HistoryOfTI.aac ! faad ! alsasink

    Setting pipeline to PAUSED ...

    Pipeline is PREROLLING ...

    Pipeline is PREROLLED ...

    Setting pipeline to PLAYING ...

    New clock: GstAudioSinkClock

    Got EOS from element "pipeline0".

    Execution ended after 18371633002 ns.

    Either the pipeline provided by me or the pipeline provided by Joe G will produce audio playback.

    gst-launch-0.10 audiotestsrc ! alsasink

    produces a test tone on the audio output.

    gst-launch-0.10 filesrc location=/usr/share/ti/audio/HistoryOfTI.aac ! faad ! alsasink

    will playback a short audio clip on the output.

    The pipeline you have used is using fakesrc and fakesink which will not generate any sound.

    Hi Dave Gerlach & Joe G,

    When I run the commands sent by you its getting hanged at clock..

    root@am335x-evm:~# gst-launch-0.10 audiotestsrc ! alsasink

    Setting pipeline to PAUSED ...

    Pipeline is PREROLLING ...

    Pipeline is PREROLLED ...

    Setting pipeline to PLAYING ...

    New clock: GstAudioSinkClock

    Thanks and Regards,

    Rajeev,

    Do you have a speaker our headphones connected to the audio output of your board? This is where the pipeline sits while it is playing, it should be producing audio output at this point. You can exit the pipeline using Ctrl+C.

    Regards,

    Dave

    Rajeev,

    You may need to configure the volume setting of the audio hardware to make sure it is at an audible level. You can use amixer to set this:

    amixer cset name='PCM Playback Volume' 127

    Regards,

    Dave

    Dave,

    Following is the error i faced when i tried to execute the command.

    root@am335x-evm:~# amixer cset name='PCM Playback Volume' 127
    amixer: Control default open error: No such file or directory

    Rajeev,

    This command should run without issue on our SDK if it is unmodifed. Have you made any changes to the kernel or file system? Do you know what version of the EZSDK you are running? If you run

    cat /proc/asound/devices

    at the command line, can you post the output?

    Regards,
    Dave

    Dave,

    Out put for cat /proc/asound/devices

    EZSDK is  ti-sdk-am335x-evm-05.05.00.00

    Yes we did updated codec driver in kernel.
