Phil,
As discussed, we seem to have now identified the core issue which does appear to be a software problem in the Beosound 9000, the fact that no one else has previously reported it other then you, does not mean there is not a problem.
After doing some further research, I think the problem is likely to occur, not at the 200 titles level, but 255 point. At this point the EEprom would get a "Write Overflow". The reason is because up to 255 uses 8 bit addressing and to go to 256 titles would need 9 bits. It seems likely that the software is not handling the write overflow correctly. In fact diagnostic test 28 does appear to test this function and I am assuming the B&O engineer did run the diagnostics tests without problems.
Whilst you have always been able to delete title names, its not clear to me yet if this action also deletes the CD id code as well.
So, we need to do a test to determine if deleting a name also deletes the CD id code as follows:-
- Open Beosound control panel lid.
- In the second section from the right on the control panel press CD and allow a working CD to play.
- Below press NAMING button twice and you should see on the display the words CD LIST
- You can use the up and down arrows to review your CD titles if you have any stored.
- With a CD title listed press CLEAR and it will be deleted
- Now delete, say 10 titles
Stop any CD that is playing and add a new CD which has not been on the unit before, if this works without problems, then we know that deleting a title entry ALSO deletes the CD id and makes the memory location available for a new title.
If the CD fails in the normal way, then we know that using the CLEAR function does NOT delete the CD id from memory or leaves the memory location marked as allocated, either way we will need to find another way to resolve the issue in the form of a workaround.
