Mismatched sample rates causes boot failure.

npes-95 commented 4 years ago

I was trying to use Sonic Pi (macOS 10.14.6, 2012 MBP) with a BT speaker, but was unable to launch it due to a sample rate mismatch (in: 8kHz, out: 48kHz) - at least this is what I understood from the log:

The proposed way to resolve the issue (in the error message) won't work as we can't boot and access the settings. Let me know what you think of this and I can provide additional details as necessary.

Hi @npes-95. The above is a known issue, as described in #1856, (See Sam's comments there) which will be fixed as of the next release (or you can compile master branch yourself to get the fix for that now).

Hi @ethancrawford, thanks for getting back to me! I hadn't seen the issue, my bad :)
