Android Irish no audio (resolved!)
I get audio on the website, but not on the Duolingo app [on Android]. There's not even a speaker button to replay the audio. I try on iOS and there's audio. I haven't found a lesson that has audio on Android, but I only have 3 subjects available to me (i.e.: I've only completed the first row of the tree).
I have rebooted the phone, deleted cache and storage, uninstalled the app, and re-installed. I now have a speaker, but no audio when a lesson starts and none when I press the speaker button. Tried putting sound all the way up, but it's quite a shock when the "ding" occurs at full volume at the end (still no audio from lesson).
after a few more reboots and deleting cache and storage (and was there a new version?), it's now working!
If you're having a problem with the app, it's a Duolingo problem, not a problem with the Irish course - there isn't a special version of the Irish course for Android.
As the only people reading the comments here in the Irish discussion threads are ordinary users just like you, there isn't anything that anyone here can do about this problem. You should move your post to the Troubleshooting forum, where it might get higher visibility, and you should also submit a bug report (see the "Help" link at the bottom of the page) to bring it to the attention of the people at Duolingo that can do something about problems with the various Duolingo apps.
I often use the Duolingo Android app (have used a couple different versions of Android for that matter), and Duolingo on a browser/PC. A lot of lessons simply do not have audio, but I haven't noticed any difference in availability between the two platforms, and I've not noticed problems with audio on Android. And there is more audio and better than there used to be - ignore the many three year old complaints about the original recordings.
On the other hand there is one huge difference between the platforms to be aware of: on a browser there are instruction notes for each lesson, they are really helpful as you make your way through the course.
Since the recent website redesign with the Crowns, it is now possible to read the Tips & Notes in the browser on a mobile device, something that used to be difficult, if not impossible. It's not the same as accessing the notes in the app (and the vast majority of app users will never discover that the notes are available), but for people using Duolingo on a mobile device, there is now a way to read the Tips & Notes.
