[ALi] (with pci ids : 0x10b9 0x5451) irq 5 has been allocated to ali snd card, pcmcia cardbus controller (managed by yenta_socket). olivier is the owner of that fscking chip. this is a compaq laptop. i have access to another compaq laptop that works well with oss trident. this is a compaq laptop too. kernel is 2.4.18 based and alsa was tested with 0.9.0rc3 & rc5 ------------------------------------------------------- This SF.net email is sponsored by: ApacheCon, November 18-21 in Las Vegas (supported by COMDEX), the only Apache event to be fully supported by the ASF. http://www.apachecon.com
