In order to be able to use the USB port, I have compiled on it a 2.2.19pre16 kernel. It all works very well except that I cannot get sound working after the laptop has been in suspend mode. After a resume from suspend mode, if I try to play a mp4 sample, I only get some hashed, repetitive and disconnected fragments of the original tune. In the logs, I get the message Sound: DMA (output) timed out --- IRQ/DRQ config error ? The sound subsystem is compiled in the kernel (not as a module). Here is some relevant part of /proc/sound (copied by hand, so there might be some typos or omissions) OSS/Free: 3.8s2++-971130 drivers Type 42: OPL3SA2 Type 45: OPL3SA2 MSS Type 43: OPL3SA2 MIDI Type 1: OPL-2/OPL-3 FM Type 5: Roland MPU-401 Type 26: MPU-401 (UART) OPL3SA2 at 0x370 irq 5 drq 1,0 OPL3SA2 MSS at 0x530 drq 1,0 OPL3SA2 MIDI at 0x330 irq 9 drq 1 OPL-2/OPL-3 FM at 0x388 irq 9 drq 0 Audio devices: 0: MS Sound System (CS4321) DUPLEX apm version is 3.0beta9. I remember I had some similar problem with sound on this machine with the previous kernel (standard redhat 6.1 kernel), but I never really paid attention: as the sound was a module, I could reinitialize everything by unloading and reloading the module. So it is quite probable that this problem is an old one which has nothing to do in particular with 2.2.19pre16. If there is some missing information, or if you want me to try ?omething, please don't hesitate. And by the way, is there a way to reinitialize the sound subsystem when it is not compiled as a module ? ?ric Brunet - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
