      Has anyone been able to overcome the fast 'Chipmunk' playback speed? Apparently several (if not all) people have this issue and have been unable to resolve.

      Yes - very frustrating. A fix would be much appreciated!

      Same issue here. Playback is way too fast. Could this be a driver problem?

      I have today received this card, and can report that I have the same issue with the latest version of the SDK. I have built the system from scratch, and also used the supplied image. Both exhibit the same issue.My suspicion is that there is an issue with the provided driver.

      It seems to be an issue numerous mic HATs are having. We are looking into it, but have not yet found a solution. It does not seem to be on our end, but will will continue to try to find the problem.

      Haven't tried the solution yet. Hopefully it works.I do find it surprising that there are six reviews, all with 5 stars saying 'Good Product!' - are these shill reviews? Especially during the period that no one could come up with a solution.Be forewarned...

      It appears this board does not contain the serial EEPROM required for the Raspberry Pi HAT specification. Can you confirm?

      Hi Rich,this board doesn't contain the EEPROM, sorry for confuse of the name with "HAT". We just wanna to show this is the extension board of Raspberry Pi.Enjoy hacking.

      It seems that many HATs does not have EEPROM. If I'm not mistaken it's optional, and even if it's there it's usually useless.

      It's not OPTIONAL of HAT's specification,but just useless right now :(

      Hi, I use this board on top of the Raspberry PI Zero W, and it can not even run the google-assistant-demo, the error msg is "google.assistant.library.assistant.UnsupportedPlatformError: armv6l is not supported".

      Don't hold your breath. I (and several others) have playback issues with the speed being too fast. ZERO response from Seed forum or Seed itself.

      The button triggered demo worked for me. I believe there is a limitation of the google-assistant-sdk for running hotwords on zero.My next attempt will be to use a hot word from https://snowboy.kitt.ai/

      I fixed the chipmunk voice problem by taking the asound.conf and asound.state files from the source dist of the re-speaker driver on github and installing them according to the instructions (put asound.conf in /etc, use alsactl command to install asound.state), then I used alsamixer to increase volume on all device (mic and speaker). It Works!

      @Bob Thanks for the info! Could you provide the link for the 'the source dist of the re-speaker driver'? It also would have been helpful had you posted this as a response to the existing 'Chipmunk issue'. Was this under Jessie or Stretch version of Raspbian?

      Is it correct that using the JST connector for audio out I only get mono sound while using the 3.5mm audio jack I get stereo?

      Both JST connecter and 3.5m audio jack can stream audio output, are support stereo.Did you try ALSA cmd to setting?

      Xiaobo - you are wrong. There are only two pins on the JST audio connector and stereo would require 4 pins. A quick check of the schematic link shows the JST connector is wired to the right channel; the left channel LP (low power) connections on the WM8960 IC are not connected to anything. Looks like Seeed rushed to get this design out without fully thinking the design through.

      I got the answer from the technical support :It communicates through I2S (Inter-IC Sound) and it uses the pins : GPIO18 (pin 12), GPIO20 (pin 38), GPIO21 (pin 40) and GPIO19 (pin35)
