A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1213> ====================================================================== Reported By: shensche Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 1213 Category: PCI - via82xx Reproducibility: always Severity: major Priority: normal Status: new Distribution: Debian (derived Knoppix->Morphix->Kunnafonix) Kernel Version: 2.6.11.12, but also many other 2.4 and 2.6 kernels ====================================================================== Date Submitted: 06-27-2005 12:22 CEST Last Modified: 06-03-2006 15:50 CEST ====================================================================== Summary: snd-via82xx on EPIA-M - 0 analog subsections not ready: no sound Description: i am working on a machine with an EPIA-M mainboard and the ICEensemble VT1616i sound chip (see attached lspci -v). unfortunately, i cannot hear any sound from it. it is always the same: the mixer settings seem ok, the applications play happily the files, but i cannot hear a thing. the speakers are ok, too. the system is running kernel 2.6.11 with the kernel patches from Con Kolivas (-ck10) and ALSA. i also tried OSS (not the emu) on that kernel. i tried 2.4 kernels with Damn Small Linux and Knoppix 3.7 and 2.6.9 =66rom Knoppix 3.7 and a custom 2.6.10-ck6. since ALSA 1.0.8 did not work, i installed 1.0.9b, including the libs and utils. during that upgrade, the mixer lost the possibility to change the DXS-settings. has this to do with the whitelist, introduced recently? i played around with lots of combinations of the options ac97_quirk and dxs_support when loading the kernel module. on the hardware side i disabled the front panel sockets for line-out and mic-in, just to be sure. and i often tried all three sockets for=20 line-out, line-in and mic-in in the back to hear the output. the chip seems to share interrupt 10 with USB, so i unloaded uhci-hcd, but to no avail. i also dis-/enabled ACPI, reserved IRQ for non-PCI (now USB and sound share interrupt 5) in the BIOS. the BIOS was told that there was a/no PlugNPlay OS and the MC97 modem is disabled. the machine does not seem to have an APIC. i muted some IEC 958 settings in the mixer as read somewhere in the net, but that did not help either. and one of these settings always reenables itself as soon as i try to play a wav with aplay. i modified alsa-kernel/pci/ac97/ac97_codec.c to goto __ready_ok also when "0 analog subsections are ready" (weird message, btw) before line 1960. another try was to increase the end_time in line 1953 by factor 10. both did not yield a successful result, both being a shot in the blue. i attached /etc/asound.state (after saving with alsactl store) and the output of dmesg. do not mind the oops from cowloop, i guess it is not important, because all the other kernels do not work as well. i read=20 http://alsa-project.org/alsa-doc/doc-php/template.php?company=3DVIA&card=3D= =2E&chip=3DVIA82C686%2C+VIA8233%2C+VIA8233A%2C+VIA8235&module=3Dvia82xx alsa-kernel/Documentation/ALSA-Configuration.txt and many other forum entries but still something is going wrong. why are 0 analog subdevices ready? how to make them ready? where to wait? what to initialise? i will try to upgrade the BIOS, soon and try with MS Windows (if i manage to fit it onto 1 GB) ====================================================================== ---------------------------------------------------------------------- wouter - 06-02-06 09:52 ---------------------------------------------------------------------- I have a Via Epia M-10000, I can't get the sound working either. I've been trying remote (!) for almost a year already (the machine itself is in Kuopio, Finland; I'm in Brussels, Belgium at the moment). lspci: 0000:00:11.5 Multimedia audio controller: VIA Technologies, Inc.

[...] ---------------------------------------------------------------------- picobyte - 06-03-06 15:50 ---------------------------------------------------------------------- I have a via 8235 also, not working. It used to work and somewhere in kernel upgrades and/or alsa upgrades it stopped working. I succesfully had it once in alsa 1.0.9b with an early 2.6 kernel (I am not sure which one exactly since I did a kernel upgrade quite often, but I think it worked from 2.6.0-2.6.10).
