Hi, This is a well-known issue, yes ;) So I have browsed http://acpi.sourceforge.net/dsdt/view.php but I did not see my model (aka PSPAGE-00S011FR) so I don't know what to do. Could someone help me to fix my buggy DSDT in order to make work sound with ACPI please ? Should I send more information (as outputs of dmesg, dmidecode, acpidump, lspci -vv& /proc/interrupts) ? PS : here is attached my DSDT file (from acpidump). PS2 : my BIOS release is uptodate (3.30) Thanks in advance. Cheers, -- http://scipy.org/FredericPetit
