Getting “No audio files” in your car stereo with iPhone?

Recently, I was surprised by a “No audio files” issue that prevented me to push any sound to my car stereo system using the USB cable. It was working fine before and It works fine by Bluetooth, but in a car with Waze or other mapping tools and music playing without charging is bad.


  • √ It was working great before
  • √ iPhone works fine with Bluetooth
  • √ Other iPhones work fine, so no problem with the car stereo
  • X I can get power with connected through USB, but no audio is playing in the stereo.

The problem

After a few weeks, I decided to dig a little bit and look for the issue and do some tests.

I found that for car stereos, connecting through USB is really like a USB, the device needs to have media, and that on iPhones means music in the Music App. So, my problem was that I offload the Music App on iPhone, so no more media was available for the connection. After plug the iPhone it gets an error on the car stereo.

During this analysis, I found that other issues can happen with your connection of your iPhone with your car stereo:

  • Your Music App isn’t installed or active
  • You don’t have any media in your Music App
  • Your cable is damaged and won’t charge or play music

Note: If you have car play, probably you won’t get this issue. This is for simple car stereos.

I found this issue on a Nissan Qashqai connecting an iPhone X with iOS 14.6, but saw similar issues on Mazda car stereos and other iPhone versions.

The solution

Make sure your cable is in good shape and you have Music App with some music on your iPhone.

Enhanced Google Analytics tracking (beta)

Google Analytics is one of the most powerful analytics tools out there, even though many non technical users think it’s too complex.

To simplify the usage of Google Analytics tracking, I’m working on a enhanced version of the tracker, an addon that can help a lot of non-technical marketeers and web analysts.

The Enhanced Google Analytics (eGA) tracking, as I call it, will track:

  • File Downloads
  • Scroll
  • Time on site
  • External link


How eGA works?

eGA uses GA events to measure all the micro actions:

Real time events for eGA


How to install eGA?

You can just add the following script to the end of the page, before closing the body (</body>):

<script src=”ega.min.js” defer=”defer”></script>

I used the defer attribute to be completely async and we could think to put it in the head, but I’m asking to put it in the footer anyway to be sure that it doesn’t delay your website.

eGA allow you to set the domain and the time interval:

<script src=”ega.min.js?″ defer=”defer”></script>

Heavenly Sword (PS3) – Deflect Bohan attacks

To win the final battle (Redemption) in Heavenly Sword without too much effort we’ve to know how to block and deflect Bohan (Raven King – The Boss) attacks back to him, specially those sent from the air.

Bohan throws two types of projectiles, blue (Speed Stance) and yellow (Power Stance). To deflect this attacks and sent them back to Bohan you’ve to wait until the lightning hits the sword, just when it touch you (Nariko).

  • Blue projectile (Speed stance) – Deflect this attack by pressing Triangle (Speed Stance) in the right moment
  • Orange projectile (Power Stance) – Deflect this attack by pressing R1 + Triangle (Power Stance) in the right moment

Besides, Bohan also throw this projictiles when he’s on the ground. You can block and deflect this attacks too, by using the same technique listed above.

When Bohan is in the air, he also throws ravens. This is a much easir attack to avoid and you can do it by pressing L1 + Square (Long Sword Stance).

When we get the way to deflect the attacks it’s easy to end the game, even in hell mode.

See a Youtube video of how to deflect Bohan attacks.

This games is really good and allow us to spend some gome time playing for Nariko and Kai. Good history and great play mode.
