I'm mainly saying the driver shouldn't be doing it directly, it should be doing something much closer to hwparams for digital formats. > This is a typical use case we see, > - [stream-1] Lets say high resolution audio is playing (96kHz, 24-bit, > stereo) > - [stream-2] Randomly system notifications of small durations come (48kHz, > 16-bit, stereo) > The requirement is, both streams should be mixed and played. Most systems like this would run the output at a fixed sample rate here so there'd be no runtime configuration. > Is there a better way for user to configure custom audio paths? Fit what you're doing into DPCM. It's not particularly great but it's what we have at the minute. This isn't me not understanding your use case, this is me saying that it would be better to either work like other existing drivers or improve the framework so that it works better for everyone.
