I checked a few M.I.B backups and I could find that coding in quite a lot of them. Could it be more generic? |

Wait, there will be a function in M.I.B in the near future ;) |

It could well be more generic but I didn't know how much. I know my solution works on A3/A4/A5/Q5 MKII. |

We will compare the whole string included crc before replacing it. @Mr-MIBonk will look into an implementation in the near future. We will update you here (and ask you to run some tests ) |

Thats my point. You won't need any additional software for my method. 5F is the MIB2's address and so any script in M.I.B. is already running on 5F. You just need to point at the right memory space, check if the subwoofer control is hidden and if so replace that memory space with the value that enables the subwoofer control. It doesn't get any easier than this. I only provided this method to help this project since it's Free and unless people contribute to it, it won't progress. |

this one was quick and dirty, no guarantee, that it will work - it might just do ;) If you find any issues, please post M.I.B LOG as well |

Hello, I have an Audi A4 B9 Avant with MHI2Q_ER_AUG22_P5092 MU1329 MMI with 10 speakers (8+center+subwoofer) 9VD Audi Sound System. It should be capable to enable subwoofer controls. |

@brucemiranda , share your thoughts please. In desperate hopes for bass, and better sound overall ,ive done the following , A friend was stripping out his a4 b8.5 , so he gave me the amp and connector block for amp. If this works then ill share my efforts and findings, if not my last effort will be to trade the car in for a 2020 a5 with B&O at the end of the year then no more sound issues |

Hallo zusammen, kurze Nachfrage, wie kann das Subwoofer Menü denn angezeigt werden? in meinem MIB zeigt es unter multimedia_system diesen Punkt nicht an. Oder muss zuerst der Datensatz extrahiert werden und mit dem tool angepasst werden? Aber erstmal wirklich großes Lob das die Entwickler. |

Please help. 2016 A3. 5.8" Display, no carplay or navigation. Upgraded to a 7" 2019 A3 Display and MMI. Now have carplay,bigger screen, better graphics. Everything works just fine, but the subwoofer seems to have gone silent and the option to adjust it is also gone. Any clues? I did have the option to adjust the subwoofer in the old display. |

All the basic information is available in this toolkit to enable the hidden subwoofer menu in the Audi cars that have the Audi Sound System. e.g. B9 A4/A5 Q5 MKII A3 etc. and other brands:

NEW: https://mqb-blog.com/en/2023/04/17/sound-settings-editor/
https://mqb-blog.com/en/2022/02/21/sound-dataset/
Thanks to @NumberOneBot for his research into the datasets!
Requirements:
This should now work for Audi, VW, Skoda and Seat as longs as certain criteria are met - based on coding:
No static datasets will be applied.
A custom dataset is created based on the dataset originally on unit.
Before patching a backup of the original dataset is saved to /backup/ folder and can be restored.
Two functions:
Please MIND:
CRC calculation of the very long 0x3000 dataset will take about 2 Minutes!
_Please share pictures of the changes to the GUI
And report back on function!
GEM Screens:
Please share your LOG files in case of issues, but also if all is working fine :)_
