  and later.

  configure : aarch64 : Support assembling the dotprod and i8mm arch extensions
  These are available since ARMv8.4-a and ARMv8.6-a respectively,
  
  but can also be available optionally since ARMv8.2-a.
  Check if ".arch armv8.2-a" and ".arch_extension dotprod,i8mm" are
  
  supported, and check if the instructions can be assembled.
  Current clang versions fail to support the dotprod and i8mm
  
  features in the .arch_extension directive, but do support them
  
  if enabled with -march=armv8.4-a on the command line. (Curiously,
  
  lowering the arch level with ".arch armv8.2-a" doesn't make the
  
  extensions unavailable if they were enabled with -march ; if that
  
  changes, Clang should also learn to support these extensions via
  
  .arch_extension for them to remain usable here.)

• I tried to play the audio on Alexa skill from my S3 Bucket, from the test tab, **it show but in fact, I can't hear any sound

  19 avril 2022, par Siti Mayna

  So I tried to play the audio on Alexa skill from my S3 Bucket, from the test tab, it show but in fact, I can't hear any sound. Another fact is, that I tried to use the sample audio from https://developer.amazon.com/en-US/docs/alexa/custom-skills/ask-soundlibrary.html and it is worked, but why it won't work when it comes from my own S3 Bucket ?

  


  Notes :

  


  I've tried to test the skill using my mobile phone also.

  


  I've tried to encode the audio using FFmpeg.

  


  I've tried to use Jovo to convert the audio. https://v3.jovo.tech/audio-converter

  


  I don't know how to fix this error.

  


  There is no error message on cloud watch.

  


  Assumptions :
There is some problem related to the audio resources or there is more set to play audio from S3 Bucket since the sample audio is working.

  


  Steps to reproduce :

  


  


  Build the interaction model

  


  


  


  Encode the audio to make it Alexa skill friendly (fulfill the requirements, like sample rate, etc), I used and tried all of these :

  


  


  A :

  


  ffmpeg -i  -ac 2 -codec:a libmp3lame -b:a 48k -ar 16000 -write_xing 0 


  


  B :

  


  ffmpeg -i  -ac 2 -codec:a libmp3lame -b:a 48k -ar 24000 -write_xing 0 


  


  C :

  


  ffmpeg -y -i input.mp3 -ar 16000 -ab 48k -codec:a libmp3lame -ac 1 output.mp3


  


  


  Upload the audio resources on S3Bucket
Audio sample on s3 storage but none of them are produce any sounds

  


  


  


  Use the link and insert it to APLA.json

      }
    }



  


  notes : I change the link sources based on audio that I tried.
