600m PCMCIA audio problems
I have a VXpocket v2 PCMCIA audio card that is working with ALSA 0.9.4.
However, when it's in use by any application, system CPU load goes up
to about 40%, and I can't play back and record at the same time without
getting pops and dropouts. This is with kernel 2.4.21 with low latency
and ACPI patches applied (I've tried booting with pci=noacpi and
acpi=off without luck).
I guess this is a driver problem, but I don't know if it's with ALSA or
the kernel PCMCIA drivers. I've sent a couple of emails to the
alsa-user mailing list, but I haven't received any replies, and I'm not
sure where else to ask. Is anyone successfully using a PCMCIA audio
card or a PC card of any kind with a Centrino-based laptop?
