Since upgrade to Kernel-2.4.x (currently 2.4.10) I got problems recording sound causing following error message in /var/log/messages: Sep 30 15:53:16 osiris kernel: Sound: DMA (input) timed out - IRQ/DRQ configerror? It's a redhat dist. (7.0) with a Yamaha ISAPnp Soundcard (OPL3 YMF719) and a self configured Kernel-2.4.10. With 2.2-Kernels and the isapnp tools (pnpdump/isapnp) the soundcard worked fine. But with the same isapnp.conf and module parameters (irq,ioports,dma) and Kernel-2.4.x the soundcard is recognized, modules are loaded successfully and any kind of soundfiles can be played, but recording like 'rec /tmp/soundfile.au' oder 'cat > /tmp/soundfile.au < /dev/audio' does NOT work anymore. I also tried the new isapnp support (included since Kernel-2.4.x) as module or directly in the kernel. Here is the output of 'dmesg': isapnp: Scanning for PnP cards... isapnp: Card 'OPL3-SA3 Sound Board' isapnp: 1 Plug & Play card detected total ad1848/cs4248 codec driver Copyright (C) by Hannu Savolainen 1993-1996 ad1848: No ISAPnP cards found, trying standard ones... opl3sa2: Activated ISA PnP card 0 (active=1) opl3sa2: chipset version = 0x4 opl3sa2: Found OPL3-SA3 (YMF715E or YMF719E) at 0x100 at 0xe84 irq 5 dma 1,3 at 0x300 irq 5 opl3sa2: 1 PnP card(s) found.

Moreover I checked another ISAPnp soundcard (Soundblaster), which also worked perfectly with Kernel-2.2.x, but with Kernel-2.4.x it's behaviour is just the same as with the Yamaha soundcard: card recognized, modules loaded successfully, soundfiles can be played but NO recording !!! What can I try else or did I forget anything ? Thanks in advance for your help ! Cheers, Phibo
