Hello, > is anyone else working on adding audio support for > the neomagic 256av chipset yet? To current or stable? I have Dell Inspiron 3500 with neomagic 256av audio working under stable. > this is all very new to me.. but i have lots of time > and a definite need to listen to mp3s on my laptop... > so if i can get a foothold, i'll try to get it done. I have mpg123 running ok. Only caveat, If I suspend then mpg123 wont work on resumption, it appears that the buffers still have some data in them. (get a repeated loop of sound). Also see tsleep messages. When using modem I get "/kernel: How strange... mss_intr iwith no reason!" but everything continues to work (I mam not using the audio). I rarely (almost never) use the audio thus haven't bothered to chase it any further. > i've read luigi's paper on the new audio driver > (http://www.iet.unipi.it/~luigi/sound.html) > any other recommendations to help me get up to speed? Most of the problem is avoiding clashing interupts (and finding a free one!) I sent this to someone else who asked about how to get it running (I never heard back so I dont know if they were successful or not) tonym ----------------------------------------------------------------------------- This is the relevant config details: Kernel: controller pnp0 device pcm0 at isa? port ? tty irq 7 drq 0 flags 0x11 Dell PhoenixBio 4.0: System devices: Serial port Customised # probably could go back to auto [3F8 irq4] # I just like to see what things are Infrared port Off parallel port Off # I need the interrrupt for sound Audio Customised SB IO address 280 WSS IO add 530 AdLib IO add 388 Interrupt 7 1st DMA channel 0 2nd DMA channel 1 I run pccardd with 2 cards permanently inserted Slot 0 DE660 Slot 1 Psion Gold Card Modem #pccard.conf # Generally available IO ports io 0x240-0x360 # Generally available IRQs (Built-in sound-card owners remove 5) irq 5 10 11 13 15 # Available memory slots memory 0xd4000 96k card "D-Link" "DE-660" config 0x20 "ed0" ? 0x10 insert /etc/pccard_ether ed0 link0 -link1 remove /sbin/ifconfig ed0 delete # Random modem bundled with Dell systems card "Psion Dacom" "Gold Card Global 56K+Fax" config 0x23 "sio3" 9 ### not the default ### insert echo "Psion Dacom modem card inserted" remove echo "Psion Dacom modem card removed" "pccardc dumpcis" showed that the DE660 only worked on irq 5 and "pccardc rdmap" showed that it used I/O address 0x240 (which could be cos pccard.conf said io can be in this range) So I changed the Audio bios to not clash with this. Maybe the entries could be tied down further but I just got everything working last nite (the sound that is, everything else was running within a couple of days of getting machine) dmesg: ....<delete>...... ... try to identify the yamaha pcm0 at 0x530 irq 7 drq 0 flags 0xa211 on isa mss_attach <mss>0 at 0x530 irq 7 dma 0:1 flags 0xa211 ....<delete>......
