View Full Version : Windows 10: Master volume amplified

This isn't really a LMS matter, again. But I found it while investigating Squeezelite-X, so...

I recently noticed that the master volume is amplified. I don't know why or how. The green bar on the left (Speakers) shows the same audio output as the tiny little one from squeezelite-win:

26944

If I switch to another audio adapter, both bars have the same height.

I changed the drivers to a recent one (from Synaptics, who apparently bought Conexant), but it made no difference.

Anyone here knows why this would happen?

Try changing drivers in Squeezelite-X. With ASIO or DirectSound, squeezelite-win should disappear from the Volume Mixer. After making that change, I wonder if you'll still be able to hear whatever that is. (ASIO sounds best to me. I don't use WASAPI because with squeezelite it's still limited to 44.1 as far as I know.)

Thank you for your response. I should've mentioned that this amplifying happens with all audio sources (VLC, Firefox etc.) As for squeezelite-X's noise, that's a different matter.

Could be a ground loop or other electrical noise in your system. Maybe change connections around? What is your hardware? How is it powered?

It's an ASUS UX32LN (https://www.asus.com/Laptops/UX32LN/) with a "Conexant SmartAudio HD" sound adapter. Which seems to be not so great.

There are not that many connections to change. There's a 3.5mm stereo jack connected to my Logitech 2.1 speakers. But even if I pull this only connection, the same happens with the inbuilt speakers.

+1 on a USB DAC. That's the first basic upgrade to make. At the very least, you should borrow one as an experiment.

On even my best most powerful i7 laptop, the design is arranged in a way that can induce high-pitched sounds from the graphics board into the sound board, so I don't use the internal sound card at all.

What you've got there may be far better than the Realtek garbage in most PCs, but if you're on this forum it's quite likely you'll never be happy with the stock sound board in your computer anyway.

You're both right, of course. Right know I'm quite comfy with external keyboard, mouse, speakers and displays. But for travels, I only take the notebook. ;) And the volume is ridiculously high. I think I have to set the master to 2 (from 100), otherwise I'd be deaf by now.

I just installed the original (Windows 8.1) driver provided by ASUS, and it made things worse: Now it seems that changing the volume in SLX (note: I don't blame SLX here, but this "&(%%! driver) not only changes the volume but also equalizes things. On low volumes there's barely any low frequencies, just high frequencies, on high volumes it's the other way round.

This only affects this Conexant adapter. The Intel Audio driver (which is gone now, after I installed the Conexant drivers. WHY.) doesn't sport this behavior. Maybe it's just the driver that never got updated to work with recent systems.

As for the noise: Maybe it really is the graphics adapter. But I disabled all recording devices. Where should Windows get information about the noise? And why only from squeezelite?

Edit:

After uninstalling all the drivers and restarting the notebook, this amplifying madness stopped, some standard driver was used. And then Windows decided to reinstall the driver.

I think this is some loudness war thing. Output is maximized to whatever the master volume is set. Also, I can hear the sound compressors working. Annoying AF. The one thing every limiter needs is a bypass button.

I changed the driver to the standard "High Definition Audio Device" and the misery stopped.

Further investigation showed that some drivers come with Waves MaxxAudio. In my case, it was "just there", messing with the sound, with no indication that it was installed, as there was no UI. From what I learned, the UI is as crappy as the sound it produces. And no, it has no bypass button. You should know better, Waves.

This doesn't help with the mystery sound coming from SLX. But at least it isn't amplified any longer.

Thank you guys for your input here!

Thank you, I'll take a look!

I have no clue about your sound device but the smartest task whenever "Conexant SmartAudio HD" is involved is get rid of the driver and use another one instead.
"The Driver" not the hardware sound device!

Yes, that beats prying the sound chip out of the notebook. :p

I don't use WASAPI because with squeezelite it's still limited to 44.1 as far as I know

I've added support for WASAPI exclusive mode to the latest squeezelite-win 1.9.1-1139 (https://sourceforge.net/projects/lmsclients/files/squeezelite/windows/squeezelite-1.9.1-1139-win32.zip/download)

-a <l>:<e> Specify Portaudio params to open output device, l = target latency in ms, e = use exclusive mode for WASAPI (0|1)

First in the sound device advanced properites, you need to enable Allow applications to take exclusive control of this device

Then add -R -u E -a :1 -o "Device name [WASAPI]" to the squeezelite-win command line.

The -R -u E causes squeezelite to resample only if native rate is not supported. The WASAPI device on my laptop only supports 192000 96000 48000 44100.

I'm still working on an issue with matching devices that use utf8 characters from the command line. As a work around for now use -o X where X is the number before the device name in the output from squeezelite-win -l.
