Re: [SlimDevices: Unix] piCorePlayer, preempt, latency and cyclictest extension (request)
Thank you Paul for this complement. I thought piCore was keeping up with TinyCore which has moved to 5.15.10 with version 13. Hopefully the RPI foundation will be upgraded kernel to 5.16, faster than expected with the announce of mainline kernel support for PI compute 4. https://www.phoronix.com/scan.php?page=news_item=Raspberry-Pi-CM4-Linux-5.16 That is, if CM4s are available, which would be an upgrade opportunity for my USBridge. :rolleyes: And for the creation of a "cyclictest" extension... the tinycore forum ? zaurux's Profile: http://forums.slimdevices.com/member.php?userid=69135 View this thread: http://forums.slimdevices.com/showthread.php?t=116024 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

Is latency an issue with pre-recorded music that doesn't need to be synchronized with video? "To try to judge the real from the false will always be hard.
