Beginning of audio playback cut out


I’ve noticed that on my new laptop the first half-second (or less) of audio doesn’t play when an audio file plays automatically during review. I can go in and click the speaker icon and it will play both the audio files (male and female) with no issue, but when it plays the file after I enter the reading of a vocabulary word, it’s typically cut off.

I’m not using any additional scripts. The laptop is new, and was a fairly top-of-the-line gaming model at the end of 2021. I have a decent wifi signal (~50Mbps) but even when I was using gigabit service (in a different country) and getting >250Mbps, this was happening.

This issue seems to be the same as on this post: Sound truncated

That one didn’t seem to get resolved.

I’ve tested through the 3.5mm headphone jack, the laptop speakers, and monitor speakers via HDMI.

I’m not sure what to make of it, but it’s frustrating that my new laptop does this, while my junkie old work computer, and older laptop don’t have this issue.

Any ideas to try tweaking would be appreciated.

Do you get the issue if you have background sounds on like music?


I have the same thing, but I think it as to do with the device playing audio. There is some audio cut when I use my Sony bluetooth headset, but not when I use my wired 3.5mm headphone nor when I use my stereo speakers.

Using Windows 11 with the latest Firefox on both systems.

So I just tried a few minutes of review with music streaming in the background and did not experience this issue. All the audio files that automatically played when I got a vocabulary reading correct were the full sounds with no leading truncation.

I’m not sure what to make of that.

I’m using Chrome, on Windows 10 Home. I saw something about this being an issue with Bluetooth audio devices, but I’m not using Bluetooth.

Might be some weird power saving standard enforced by EU. I have the same problem with my speakers but not with headphones.

Interesting. I’ll see if I can find anything out from the manufacturer (Razer).

I have this issue with BT headphones thanks to power saving.

My solution was to play music at zero volume at the same time as doing reviews.

I wonder actually if WK could be modified via a user script to play a bit of silence just before the speech to work around this…


I just tried playing through my laptop’s built-in speakers again, because I realized I may actually have never used the speakers for WaniKani before (having relied heavily on headphones). So far it’s playing the full audio file, although I haven’t tested it enough to be conclusive.

(Now the issue is that I’m getting this weird “spatial echo” even though I have that feature turned off).

I’m going to try again tomorrow, as it’s bedtime, and see if it actually is an issue with using non-built-in devices (which would suck).

In my experience, the full audio is played the first time you play it, but the beginning is clipped if you play it again without refreshing/changing the page. I think the first time the audio file has to be downloaded from the server, and after that it’s cached (until the page is refreshed/changed). I always wondered if it had something to do with a bad browser optimization, but I really have no idea. I use Chrome.

FWIW, I am experiencing the same or similar on my 2015-vintage MacBook Pro running MacOS Monterey with the Safari browser.

I have not experienced it on my Windows laptop with Chrome.

I have reported the problem through WK support - but have not (yet, anyway) had an opportunity to try some of the diagnostic steps that were recommended to me.

I had initially wondered whether the issue may have been related to the recent WK software updates, however upon finding this community thread (and the link to the 2019 ‘Sound truncated’ thread in the first post above) it appears likely that what I am experiencing is in fact not something new related to that update.

I am not using BT, rather I am using the MacBook’s built-in speakers.

At least for the audio playback symptoms that I was experiencing, this issue has been resolved by the WK development team.

I continue to have this issue in Google Chrome on multiple systems by different manufacturers (Razor and Dell). The common issue is that I’m playing audio through a Bluetooth device, HDMI monitor connection, or dock. When I use the built-in speakers or a standard headset connected to the 3.5mm headset jack, there is no clipping issue.

This workaround works for me:

Workaround: Play some low-volume audio while you review. I use with the volume on the YouTube video turned down almost to zero.

I figured this out after @textheavy said it was on HDMI/bluetooth devices - I figure the device is “cleverly” trying to stop pops and clicks if an audio file suddenly plays very loud things, so having any audio continuously sent to the device seems to stop this.
