Revision 1.5, Mon Nov 1 14:43:25 2021 UTC (2 years, 6 months ago) by ratchov
Stop binding audio devices exposed by sndiod to physical devices This a shift towards a new model: clients connect to logical devices (created with -s option) then the server routes data to/from the underlying physical device (registered with -f option). The binding may be changed at run-time with the server.device control exposed by sndioctl(1). As audio devices exposed by sndiod(8) are not bound to fixed physical devices anymore, the physical audio device number component of sndio(7) descriptors was removed. fixes, help from and ok denis, edd |
