Nothing will ever come close to convenience of analogue volume knobs. They give both immediate action and infinite granular control. Same goes for kitchen stoves. All the modern touch controls with step-based control is the absolute nightmare in terms of UI.

My Topping DAC/Amp has an optical rotary encoder for volume control and it is awful, it will randomly jump 10x the amount of steps you have rotated it, sometimes even in the opposite direction. There's something to be said for a good old fashioned potentiometer.

until it wears off or catches something between the slider and the base

Potentiometers have that problem too when they get worn, which they always do if they also double as on/off switch like on most cheap radios.

Yes, I keep a can of contact cleaner around to get rid of the oxidisation.

I’ve got a microphone with a physical kill switch and when turned off it still leaks like a sieve. Be careful with those switches.

I always wondered if these physical switches are actually reliable and now reading your comment actually terrifies me. This behavior can cause irreversible social damage in say during high steak business meetings. One could absolutely sue the microphone manufacturer for this.

"It depends".

Digital built-in microphones use DMIC, which aiui is a one-wire interface where the microphone just sends a delta-sigma bitstream. If you implement the switch through a multiplexer or logic gate this kills the signal 100 % essentially.

Analog electrets can't be just shorted, because that causes a loud BANG when you switch due to the bias voltage, so you use a capacitor in series, which only shorts the AC portion. Because of the impedances involved, this only gives you 40-60 dB of attenuation, which isn't enough for a good ADC.

Similar for XLR microphones (hot+cold are shorted, not disconnected, because of phantom power).

I let my spouse, who likes the novelty of a touchscreen, talk me into a Whirlpool oven a couple years ago that is controlled by touchscreen. I had no idea it was possible to hate an oven so much. The only saving grace is that the stovetop elements are still controlled by knobs.

My office (well, former office) used to have a touchscreen coffee maker.

Why does a coffee maker even need a touchscreen? There are literally three options!

Cooking on gas is much more pleasurable than most electric stoves. There's much more "feel" to control the heat

I have encountered the opposite problem. Some speakers turn themselves off automatically when they don't detect any sound on the line for a certain amount of time. So when you want to have your monitoring application ring the alarm on the speaker, you need to be aware of it so you don't miss it. Depending on the speaker you may need to be continuously playing some very low volume audio to prevent them from auto-turni…

> Depending on the speaker you may need to be continuously playing some very low volume audio to prevent them from auto-turning off. Standard is very high frequency -- outside of audible range. It's a good hack. Especially helpful for disabling automatic gain control.

Also prevents audio drivers putting your hardware into a low-power standby state (especially ridiculous on a desktop), which causes ~1 s of lag when starting to play audio again.

I agree with him. Also, why is there no microphone mute button (or shortcut) integrated in windows? Seems like a must-have nowadays.

That has been driving me crazy. I did manage to write an applescript toggle that i associated with my F1 key. I never really trust it, though.

Oh I love them high steak business meatings, with rare proposals and well done outcomes. ontopic: all mechanical switches fail, and have multiple ways to fail, from subtle contact jitter to loose/broken springs to whatever else could break
