[VIA VT1708S] ALSA test tone not correctly played back

[Hannu Teulahti]

No sound after upgrade from lucid to maverick. No sound with fresh install of maveric.

Tested different kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/

Last one working is linux-image-2.6.32-0206322411-generic and first one not working linux-image-2.6.33-020633-generic

Motherboard is Asus M4N78 PRO

Monitor is connected with DVI, and tried this fix for hdmi monitors: http://analogbit.com/hdmi_dvi_audio, it didn't help.

Please try linux-backports-modules-alsa-maverick-generic.

[Hannu Teulahti (teu)]

Tried the backports-modules, didn't help.

[Daniel T Chen (crimsun)]

Can you run "apport-collect 664062" while running the backports driver?

Installed a minimal (no X, no nothing) Debian Squeeze with enough sw to play audio. alsa-base, mpg321 and tested the sound problem.

Sound works with linux-image-2.6.30-2-amd64, but not with linux-image-2.6.32-5-amd64. Maybe the Debian 2.6.32 has extra patches that cause the problem because the vanilla 2.6.32 works.

alsamixer has different sliders with the 2 above kernels, so there is definitely something different with those kernels.

Ok, after some studying found out that the front and rear outputs work independently and the front has 2 different ways of usage hda and ac97. My case is a bit older than the motherboard and doesn't support hda on the front panel. There is a bios setting for the type of front panel (hda/ac97). when I changed the setting to ac97 sound started working. Maybe the old drivers used the ac97 setting even if the bios setting had been wrong since when I built this system.

This bug's summary should be rewritten to: "no sound from front output when upgrading from lucid to maverick" and status to invalid.

This release of Ubuntu is no longer receiving maintenance updates. If this is still an issue on a maintained version of Ubuntu please let us know.
