Re: [Alsa-user] Multi and Format
Clemens Many thanks for the input, however I cannot seem to get the linear to work after a multi, even if after a multi -> rate -> linear -> slave. Anything that I do that specifies a format after the multi seems to fail. Is there another way you could recommend maybe instead of using the multi for sample copying?

Re: [Alsa-user] Hotone Ravo USB audio
Can I do anything to test it? Or just wait for an updated driver? Best regards, Dimitris Damigos On Τετάρτη, 7 Δεκεμβρίου 2016 1:07:55 Μ.Μ.

That request fails; this appears to be a bug in the device's firmware. In this particular case, the endpoint has only a single frequency, so this error might be harmless. It should be possible to change the driver to ignore the error.

Ideally > I want to set the analogue at 32bit and force the digital to 24bit A single PCM device uses a single format. The multi plugin just copies samples, so its slave devices must use the same format. However, you can use the linear plugin to automatically convert the sample format between itself and its slave.
