I'm using the Chrome extension in Vivaldi, and I hear no sound. Yomitan and the older Yomichan work fine.

BTW, is there a way to remove the romaji? Having both hiragana and romaji together is not good.

Edit: And for some words there's _only_ romaji.. :-(

Thanks for feedback, in some cases, we use a NLP lib to detect to language of the word since we support multiple languages, this may be due to language detection failed on some words.
