[SOLVED] Dota 2 static, cracking, and broken sound

I decided to reformat my computer and reinstall everything. Usually when I reinstall Steam, it’s an easy process.. When I finally did open up Dota 2, the music and character talk was all static sounding. At first I thought maybe it was the sound driver or video driver.  I tested this out by playing a  random YouTube video and it played fine. Which makes me think this is only isolated to Dota 2. What I’ve tried:

  • Reinstall sound driver. No change.
  • Reinstall my video driver. No change.

What worked to my surprise was the “Verify integrity of game files” feature in steam:

 

Step 1

Right click the Dota 2 in the library and the click properties

Step 2

Click “local files” tab and then click “verify integrity of game files”

Step 3

Wait until it’s done validating.

 

For me, after the files were done validating it says I had 198 instances of files that were invalidated. It re-downloaded those files and when I opened Dota 2 the crackling noise disappeared.

[SOLVED] Internet speed slower on a Mac than Windows

I was helping my friend again with his Mac he complained his internet speed is not as advertised. I went ahead and tested my internet speed via Ethernet and I resulted 250 Mbps from fast.com When testing his Apple iMac Pro I only resulted in 50 Mbps via Ethernet. I was baffled, I went ahead changed/checked the following:

  • Changed the MTU. No improvement
  • Manually set IP. No improvement
  • Changed Ethernet cable to a fancy CAT-7 cable. No improvement
  • Checked to see if there was any malware or viruses. None.
  • Nothing was downloading.
  • Checked if there was any issue with the writing speed on the SSD. Writing speed was good.

The breakthrough was when I decided to ping to google.com on my Windows laptop. What I realized was that I was getting IPv6 from google.com instead of IPv4.

So I decided to go back into the Ethernet settings and enable IPV6 since it was not enabled

Steps to enable IPv6:

  1. Apple menu
  2. System Preferences
  3. Network
  4. Choose your connection type. For me it was Ethernet
  5. Advanced Button
  6. Select the TCP/IP
  7. Change the Configure IPv6 drop-down box from Off to Automatically.

 

After enabling IPV6, I speed test the iMac and to my surprise it was finally getting 200+ Mbps. I decided to turn off IPv4 and use IPv6 alone, but unfortunately that did not work. So I left IPv4 on. Most likely when he configured his network, he accidentally enabled IPv6. At the same time I’m pretty baffled on why IPv4 is slower than IPv6.Almost 4x as slow. Maybe he configured his network wrong and so the IPv4 takes a longer route to respond? Or maybe IPv6 once enabled has a higher priority than IPv4? I decided to leave it as is since he was happy the internet was finally up to its advertised speed. Hopefully, this post becomes helpful for someone with a similar issue.

[SOLVED] Apple Mac Automatically Defaults to Proxy

So I was helping a friend’s Mac and I came across this issue where his proxy will always default to a proxy. The issue with the proxy is that once it’s on it the internet won’t work. So I would turn it off, but after a restart it’ll automatically turn back on. I went ahead and researched for possible ways to fix the issues. I discovered the main cause of this was either Malware, Trojans, Adaware, Spyware that would change the proxy settings. One way of removing it was removing LaunchDaemons. Sadly, I was not familiar with what LaunchDaemons to keep or remove so I downloaded MalwareBytes. I ran a scan and the following threats came up:

  • /Library/LaunchDaemons/com.GlobalQuestSearchDaemon.plist
  • /Library/LaunchDaemons/com.GlobalQuestSearchP.plist
  • /Users/ps/Library/Application Support/com.GlobalQuestSearch
  • /Users/ps/Library/LaunchAgents/com.GlobalQuestSearch.plist
  • /var/root/.GlobalQuestSearch
  • /var/root/.mitmproxy

I went ahead and removed it, restarted the computer and viola! Issue was gone. I was surprised that MalwareBytes was effective on a Mac. Why was I surprised? When I was researching this issue I was also researching to see if MalwareBytes was recommended to combat this solution other users commented that any anti-virus or ant-malware solutions are pointless:

Don’t use any kind of “anti-virus” or “anti-malware” product on a Mac. There is never a need for it, and relying on it for protection makes you more vulnerable to attack, not less.Malware is always changing to get around the defenses against it. This procedure works as of now, as far as I know. It may not work in the future. Anyone finding this comment a few days or more after it was posted should look for a more recent discussion, or start a new one.

And…

Anti-virus software definitely can do more harm than good. Seriously, just remove it all. There are many 20-year veterans here who have never, ever had AV software on their Macs. Just remove it.

Despite the naysayers the MalwareBytes came through in the end to help solve this issue and improve my friends situation.  Luckily MalwareBytes is free for home use and you can use the free version to solve this problem here’s the link for the Mac download:
