I'm trying to put an SB16 (It's not PnP) to work in a 3.0-current. Everything works fine except for VAT. When I start vat I get: SNDCTL_DSP_GETFMTS returns 0xb0000058 full duplex but all I get is noise. I know you have a hacked version of vat, this is the version of vat I'm using which I got from a friend of mine. any suggestions ? ^ ^ this implements AUTO-DMA mode, has been tested for several days on a ^ 2.2.1 system. It seems to work quite well in full duplex with ^ Crystal CS423x, Opti931 and even with the SB16 (and clones of WSS ^ and SB16). It works in half duplex with the SBPro, although with ^ some limitations. ^ ^ Compared to previous snapshots, this code does not suffer from the ^ problems (clicks and deadlocks) which affected the previous driver with ^ certain boards. ^ ^ I have added some code so that -current users can use the code by ^ simply uncommenting a #define USE_POLL in file sound.h ^ ^ If there is sufficient positive feedback it might be possible to put ^ this into 2.2.5 so please guy test this code. ^ ^ The code is still a bit verbose but this is done to ease debugging. If ^ you have problems please supply, in plain ascii, the following data: ^ - OS version; ^ - card type (the more detail, the better it is) ^ - dmesg output if relevant; ^ - pnpinfo output if you have a PnP card. ^ ^ Thanks for your help. ^ Luigi ^ -----------------------------+-------------------------------------- ^ Luigi Rizzo | Dip. di Ingegneria dell'Informazione ^ email: luigi@iet.unipi.it | Universita' di Pisa ^ tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) ^ fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ ^ _____________________________|______________________________________ ^ Rodolfo H G Faria
