Life is a trade-off: someone want a very hard real-time system without adopt other hardware architectures than pc (MCU, FPGA/ASIC, and so on), others want use normal and cheap pc, others want use also accelerated drivers also, others want a real-system which take care of they laptop's batteries too. And at the end we have limited resources(*) for give an answer on these needs (we are all volunteers). Obviously We can't do all these things so we have to choose: It is sad but it is the life. It is on leader, developers team and comunity choose that trade-off. Ciao, Alessio (*) In ideal world we certainly choose to work on -rt instead than on -lowlatency. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
