After applying your TBSC patches, I haven't been able to reproduce
either this or your other 'metallic sound' issue on 3.99.10 yet:
clcs0 at pci0 dev 12 function 0: Cirrus Logic CS4280 CrystalClear
Audio Interface (rev. 0x01)
clcs0: Turtle Beach Santa Cruz
clcs0: interrupting at ioapic0 pin 19 (irq 12)
clcs0: ac97: Crystal CS4297A codec; headphone, 20 bit DAC, 18 bit ADC,
Crystal Semi 3D
clcs0: ac97: ext id 200<AMAP>
audio0 at clcs0: full duplex, independent
Note that I'm using a kernel with ACPI support. Full dmesg lives here:
