Hi! It seems that I have a laptop with ALC260 codec that is absolutely silent either with alsa-driver-1.0.13 or with Realtek's alsa-driver-1.0.12-4.05b. Playing with "model=" parameter does not help. lspci -nv: ... 00:1b.0 Class 0403: 8086:27d8 (rev 02) Subsystem: 161f:2057 Flags: bus master, fast devsel, latency 0, IRQ 3 Memory at feb3c000 (64-bit,
