Hi, I have several systems with a TYAN S7025 motherboard and Realtek ALC262 chipset. I have not been able to produce any audio output. Well, that is except for one of the systems: after a variety of tweeks and tests, I got sound working on one system, but I do not know what change enabled sound to start working, and I have not been able to reproduce the effect on the other systems.
I have tested with kernels up to 2.6.33, and with ALSA version 1.0.22.1. For a non-working system, 'alsaconf' gives the following output: Unknown hardware: "HDA-Intel" "Realtek ALC262" "HDA:10ec0262,10ec0262,00100202" "0x8086" "0x3a3e"
And dmesg gives the following: HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 HDA Intel 0000:00:1b.0: irq 89 for MSI/MSI-X HDA Intel 0000:00:1b.0: setting latency timer to 64 hda_codec: ALC262: BIOS auto-probing. autoconfig: line_outs=1 (0x14/0x0/0x0/0x0/0x0) speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) hp_outs=0 (0x0/0x0/0x0/0x0/0x0) mono: mono_out=0x0 dig-out=0x1e/0x0 inputs: mic=0x18, fmic=0x19, line=0x1a, fline=0x0, cd=0x1c, aux=0x0 dig-in=0x1f realtek: No valid SSID, checking pincfg 0x411111f0 for NID 0x1d realtek: Enable default setup for auto mode as fallback input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input8
For the working system, the dmesg output is the same except for two lines: autoconfig: line_outs=1 (0x1b/0x0/0x0/0x0/0x0) inputs: mic=0x18, fmic=0x19, line=0x1a, fline=0x0, cd=0x1c, aux=0x14
Is there a method for tweaking these values on the non-working system to match the working system, to see if that works?
I've uploaded the alsa-info output from a non-working system here: http://www.alsa-project.org/db/?f=91057bfc12790688f1d257743e53d5d0ec2ce1e2
I've uploaded the alsa-info output from the working system here: http://www.alsa-project.org/db/?f=198420f14cd0062713636408640636e6d474cf94
