I recently upgraded to the X-S10 and initially had no issues. But after only 2 weeks of light use, I discovered an audio issue.
I didn't notice until I uploaded my footage onto my computer, but all my clips had static in the audio. When I turned on my camera and started recording again, I noticed that the audio gauge was jumping even though there were no discernable sounds whatsoever. I thought it may have been my wireless lav mic so I reset it, but that didn't work. I unplugged it to try to use the built-in mic, but it too had static. I then tried my two shotgun mics, but the static persisted. I even tried flipping and changing the cables, to no avail.
Mind you, at this point I had not touched the audio settings on the camera whatsoever. After searching online for a solution however, I tried every suggestion, in every combination possible, but still nothing worked. I even thought that maybe there was some sort of interference from my computer, so I turned off all of my electronics -- no luck.
If anyone else has come across this issue and found a solution, please let me know asap. I'm not remotely knowledgeable enough to even attempt editing the audio track, so a fix on the camera is the only option. If not, I'll probably just have to return it 😢
