Windows sucks, too!

Audio

• Needs a registry hack to stop audio pops.
• Windows 11 TTS stops working randomly.
• 64-bit Windows 10 Home version 1909 build 18363.900 (and probably 11) lacks audio enhancement tab. Turns out MSI decided to change that to Realtek Audio Console, Sound Effects, Nahimic, Effects ON, Volume Stabilizer.
• Audio mixer sucks since 11. Doesn't show the Xbox game bar making noise, eg https://www.youtube.com/watch?v=uNCQzwPptbA
• Settings app fails at volume mixer and Bluetooth settings, unlike the settings popup from the systray.

If you don't learn from the past you're doomed to repeat it.

Audio

• Dell
• Latitude 5501 sounds even worse than my MSI MS-16P7 due to ratting its plastic case. Interviews sound like a poor phone connection. Iron Maiden - Can I Play With Madness on the other hand is tolerable and even has some bass, almost enough for Robbie Williams - Angels, which sounds like a not-quite-tuned FM radio for the vocals (too little power), particularly noticable on U2 - Discotheque. Without "audio enhancements" disabled, its audio jack adds a rumble to videos like this. Worst audio hardware I've ever used, especially playing this. Then again, using my
