Run alsa-info with --no-upload option on both working (1.0.17) and
non-working versions, and attach the generated files.

This is for the Intel D975XBX2, which lost the front sound with 1.0.18: Soundcard is detected as Sigmatel STAC9274D.

Which I/O are you referring to? The headphone output seems unplugged, and thus the outputs are only from other line-outs, as far as I see the codec info.
