Re: [fluid-dev] alsa audio driver only accepting huge period size

Hi,

glad you got your problem sorted with a local patch to the kernel. That's the joy of open-source right there! :-)

Just a quick note: the driver in question is not specific to PostmarketOS. It's coming from mainline Linux:

https://github.com/torvalds/linux/blob/master/sound/soc/qcom/lpass-platform.c

So the "proper" way to suggest a change would be to subscribe to the relevant mailing lists, prepare a patch and send it to the list for review.

Looking at the file history, it seems like the buffer size was actually increased fairly recently:

https://github.com/torvalds/linux/commit/03f20e209d07968c410fc404b3d636dc446d3ef2

And you could even reach out to the original author of the driver and ask why period_size is fixed. There might be a good reason after all:

Cheers,
