[alsa-devel] Problem with DELL XPS M1530

[Anders Rønningen]

Hi again. Here's the results of the testing.

1. alsa-driver-hg20080217, --with-debug=full and the 
"SND_PCI_QUIRK(PCI_VENDOR_ID_DELL,  0x022e, "Dell     ", 
STAC_DELL_BIOS)," line in patch_sigmatel.c commented out.

dmesg output:

2. alsa-driver 1.0.16, --with-debug=full, but else unmodified.

dmesg output:

Now the odd thing is that after the last compile of alsa-driver 1.0.16 
... stuff works! Both HP jacks, the internal speakers and the mic work 
just fine. I don't really know what to make of it, since all I have done 
is compile like I did earlier and reboot...
