Most recent kernel where this bug did not occur: NA Distribution: Gentoo Hardware Environment: Samsung R70 laptop Software Environment: Problem Description: This is an enhancement, but it is a bit weird. I have a Samsung R70 laptop wich has a snd-hda-intel card (model: ALC262). Sound works well, I can reproduce, front mic input is correct, everything seems correct in sound working. But there is a little issue: despite this well functioning of sound, ALSA does not detect any card. Maybe this model is a minor revision of other known snd-hda-intel card?? In this case, I suppose the fix is almost trivial :) This is what dmesg says (most important things): Advanced Linux Sound Architecture Driver Version 1.0.14 (Thu May 31 09:03:25 2007 UTC). ALSA device list: No soundcards found. (...) ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 22 (level, low) -> IRQ 22 PCI: Setting latency timer of device 0000:00:1b.0 to 64 hda_codec: Unknown model for ALC262, trying auto-probe from BIOS...
Created attachment 12056 [details] Complete output of dmesg This is the /var/log/dmesg file with complete output of kernel's dmesg.
This happens with the kernel-included alsa drivers, but not with external alsa-drivers.
Ok, now with 2.6.22-gentoo-r8 I can't see the ALSA device list message, but I still see the hda_codec: Unknown model for ALC262, trying auto-probe from BIOS... Thus, I see other new message wich I didn't realize before: si3054: cannot initialize. EXT MID = 0000 Is related to this bug? If I need to try 2.6.23 I'll do.
Hey! How is this issue's status now? I've been googling, and I discovered that hda has multiple models, and they add models bit by bit. At the time, none of supplied models works for me, and this bug is very annoying as it confuses mixers (like kmix) which sometimes shows some controls, and sometimes shows even more, but levels are not preserved (as controls changes). I can help in adding the Samsing's R70 laptop ALC262 model for hda codec if you supply me information of how to discover this, or what program to run to get useful developing info. Thanks.
Still present in 2.6.24-3
still present in 2.6.27-rc8
Both messages are no real bugs. "Unknown model..." is no warning/error but just information. The error from si3054 can be ignored unless you use the analog modem (the device is likely incompatible with si3054).
