locked JTAlert audio cut off

David Herring
 

Hi,

Been searching, have not yet found an answer to this…I have JTAlert 2.50.9 running and I just turned Sound On so I can get audio alerts and what I notice is that the first syllable of everything is getting chopped off.  For example, when the thing says “Calling You” all I hear is “ing You” — the first part is gone.

I am using the speakers in the HDMI monitor for sound.  Windows sounds don’t seem to be affected in the same way.

Ideas?

Thanks!

As a first step update JTAlert. There has been an audio fix since 2.50.9 was released.

If the problem persists, try updating your audio/video drivers. Cutoff audio is a common problem with hdmi devices as the audio device is put to sleep and it takes the playing of a sound to wake it up, causing the loss of the first part of the sound.

If you get multiple audio alerts from JTAlert at the end of a FT8 period you will observe that only the first sound is cut-off with the remaining sounds being played in full. NVIDIA is notorious for this. Some hdmi audio drivers have power saving settings that can be adjusted to avoid the audio device going into premature sleep mode.

FWIW, my hdmi monitor via its driver puts the audio to sleep within ~ 3 seconds of the last sound being played.

Bummer.

I updated JTAlert to 2.51.3 — no help there. Though it is good to be up to date.

Checked the drivers…I have the latest and greatest ones, no update possible.

I googled and walked through every setting on this driver and there is no way provided to adjust any sort of power or sleep functions.

I googled and walked through every setting on the monitor and there does not appear to be any adjustments relevant to this behavior.

I’m getting the sinking feeling that this problem isn’t currently solvable.  Oh well, unless someone can think of something else, I’ll have to come up with an alternative way to hear JTAlert that doesn’t rely on HDMI.

Laurie, as always, thank you for your help!

All the best…

I use a small Blue Tooth speaker (Anker speaker from Amazon) connecting with Blue Tooth from my PC. It takes some fiddling around - I connect to “Headset AnkerSound Core Hands Free Default Device”.  It sometimes connects to another device where it chops off the first syllable. Works perfect.

It is solvable. I have done it. The trick is to prevent the hdmi device from going to sleep.

Do the following.
  • Download & install the free VB-CABLE Virtual Audio Cable pair from https://vb-audio.com/Cable/
  • Once installed set JTAlert to use the "CABLE Input" device for sound output.



  • Open Windows Control panel and click the "Sound" applet icon.
  • From the Sound window select the Recording tab.
  • Select the "CABLE Output" device. This is the other end of the cable pair to which JTAlert is connected.
  • Click the "Properties" button.



  • On the "CABLE Output Properties" window select the "Input" tab.
  • Tick the "Listen to this device" checkbox.
  • Select your hdmi device as the playback device.


This works for me.

    And you think you need HDMI to listen to JTAlert?

    JTAlert does not require HDMI for sound output. JTAlert will work with any Windows sound output device.

    The audio device in a HDMI monitor can be used, but as noted some HDMI drivers cause a cutoff in the output due to the device being put to sleep. The cutoff is the result of the device coming out of sleep, triggered by the first part of the sound play request.

    Hi

     

    My JTAlet audio is loud but not clear for years. As Dave did describe it “ the first syllable of everything is getting chopped off.  For example, when the thing says “Calling You” all I hear is “ing You” — the first part is gone”

    I am using my computer built in audio and an external speaker.

    As I review this thread, I don’t see where anyone said they “NEED HDMI” to listen to JTAlert.  Not sure where that notion came from.  What I can say is that using the speakers in an HDMI monitor that is already connected to one’s station computer anyway is certainly a convenience.

    Setting up a bluetooth speaker or deploying a $5 sound dongle and some wired computer speakers are all perfectly fine ideas (thanks folks!), quite trivial to do, and was the direction I was headed after discovering the HDMI chop-off problem I described last night.

    But I have to say, the idea Laurie has offered is very intriguing. Quite possibly I might never have thought to try VB-Cable.  Despite already having speakers and dongles and such, I’m going to try the VB-Cable trick and see how that goes.  That strikes me as just so irresistibly clever… 

    Anyway, a heartfelt thanks to everyone chiming in on this one…

    Oh by the way, Amos 4X4MF: if you are experiencing the first syllable chop off problem using your internal sound card, then I can only imagine that there is a power setting in Windows (assuming your are using Windows) that is allowing that device to go into some kind of power saving mode.  Some internal sound devices are even USB devices.  Working through all the sound driver(s) associated with all the sound device(s) in the Windows device manager, including the USB ones, and disabling anything related to sleep or power saving may address your problem.  Also, what kind of external speaker?  Is it wired or wireless. If it’s wireless that might be part of the problem, too - a wireless speaker tends to go to sleep when not actively used.

    Hi Joe,

    Yes, monitor sleep and USB selective suspend are all disabled. 

    The issue seems to be that neither the monitor nor the specific sound driver have any power settings whatsoever.  So while Windows is fully configured to neither sleep nor power down anything at this point, this driver itself is seemingly free to sleep the HDMI audio connection at will - and does.  No way available to tell it otherwise.  I’m going to try Laurie’s VB-Cable suggestion a little later to see if it will work in my situation.

    That is correct.

    Over a year ago I did some extensive research into why my hdmi monitor was cutting off the first part of the sounds. There was a lot of info about this behavior, but often hidden away is seemingly unrelated forum posts and blogs. For the Nvidia card I was using it was due to a very short power save time (~ 3 seconds) being applied. The Nvidia drivers don't expose a setting for this, it is hardcoded, but with an entry hidden away in a very obscure changing Registry entry location. Changing the Registry entry fixed the problem for a short time, but usually within a couple of days it had reverted. This Registry hack was not a suitable long-term solution.

    The VB-Cable solution seems to keep the audio device from going into this power safe mode after 3 seconds for my Nvidia card.

    The late great Bill Somerville G4WJS, of WSJTX fame, confirmed that the the VB-Cable solution worked for him as well.
