Hi, sorry for my bad English... No sound by default on FreeBSD-12.1-p2-amd64 in mini-PCs: Intel NUC5PPYH & Intel DN2820FYKH: Intel NUC5PPYH: Intel N3700 CPU Braswell, Realtek ALC283 HDA CODEC. Intel NUC DN2820FYKH: Intel N2830 CPU Bay-Trail-M On FreeBSD sound play only after sysctl tuning: sysctl dev.hdac.0.polling=1 But in this case sound plays with the artefacts (sound freeze). On other operating systems all OK with sound play by default. Tested with: DragonFly BSD, NetBSD, OpenBSD, Linux, Windows. This problem is observed only in FreeBSD with all Bioses versions and all versions of FreeBSD: RELEASE and CURRENT. Is it possible to fix this problem for FreeBSD (for sound plays OK without sysctl polling and sound freeze?) Verbose EFI boot Intel NUC5PPYH on FreeBSD-12.1-p2-amd64: https://yadi.sk/d/xdNqgdyh2KmTPQ dmitrii@nuc5:~ % cat /dev/sndstat Installed devices: pcm0: <Realtek ALC283 (Analog)> (play/rec) pcm1: <Realtek ALC283 (Front Analog Headphones)> (play) default pcm2: <Realtek ALC283 (Internal Digital)> (play) pcm3: <Intel (0x2883) (HDMI/DP 8ch)> (play) No devices installed from userspace. --- best regards, Dmitrii Postolov dpostolov@yandex.ru
