https://community.nxp.com/t5/i-MX-Processors/writing-an-ALSA-driver/m-p/1980602#M230066 <P>Hello,</P><P>I've been tasked with writing an ALSA soundcard driver for IMX8/Yocto build system. This isn't a tradidional driver which wraps an SAI port or controls a Hardware codec or other hardware but like a bridge which transfers audio from another domain in the system running under a hypervisor to the Linux world, where it can be used by LInux applications, saved/played back from files, etc.</P><P>I'm very new to Linux and IMX (but not to device programming and audio). I've found a "sound-dummy" example LInux driver which I'm working to probe and reverse-engineer but I wondered if there were any documentation or examples specifically for the IMX? (I've tried the search engine but haven't turned up much, except for the SAI port wrapper)</P><P>&nbsp;</P><P>Thanks</P> Thu, 24 Oct 2024 01:14:33 GMT sgordon777 2024-10-24T01:14:33Z https://community.nxp.com/t5/i-MX-Processors/writing-an-ALSA-driver/m-p/1980602#M230066 <P>Hello,</P><P>I've been tasked with writing an ALSA soundcard driver for IMX8/Yocto build system.
