That's a rather noisy keyboard for a portable device I think, but that might just be my concern. Also those speakers distort quite a lot when turned up high - but all speakers will distort if over-driven, so that's not always a bad thing. Be interesting to see how other devices compare, including what volume they can pump out clean audio to though.
Apparently a number of issues reported in these test WIN 2 prototypes have now been fixed ready for the production run. GPD just made an IGG update regarding this. One of the issues they fixed was to do with Audio. Here is a list of the prototype issues that were noted and are now fixed, this is from their last IGG update:
Until now, we have settled the following WIN 2 issues.
1. Corrected the display chip program bugs and settled the issue of bad screen when playing some games.
2. Corrected the audio circuit and settled plosive sound issue.
3. Optimized the grounding in SSD circuit and changed the supplier of SSD card which can avoid the SSD damage because of static.
4. Optimized the Wi-Fi chip and driver and settled the problem of abrupt disconnection of Wi-Fi.
5. Renovated the molds structure’s accuracy, including TF card slot interface gap and the keyboard button structure which can lengthen the keyboard life time.
6. Solved the problem of the structure of the screen fit which can avoid light leakage.
7. Optimized the charging circuit. WIN 2 is compatible with all the power adapter and power bank which based on PD protocol on the market.
