Hi. I'm having trouble with latest ALSA and oss emulation. I'm using dosemu to play some DOS games and I've noticed that sound in DOS apps stops playing after short time (depending on the app).
I'm regulary updating both alsa and dosemu, I suspected dosemu first, since I had no problems whatsoever with alsa oss emulation. It turned out that this was not dosemu problem, but alsa oss emulation problem. I've tracked it down to a change in alsa-kernel/core/oss/pcm_oss.c. The change is here: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/alsa/alsa-kernel/core/oss/pcm_oss.c.diff?r1=1.40&r2=1.41 I'm currently using the latest pcm_oss.c but without this patch and it works great again. I think that dosemu code - src/arch/linux/dosext/sound/linux_sound.c is correct. Anyway, here's a couple of lines from dosemu sound log, starting arround where IOCTL error appears: SB:[Linux] Get Free Fragments (16, 0) SB:[Linux] Get Free Fragments (16, 0) SB: Read 0x7f from DSP Write Buffer Status Register SB: Going to write 128 bytes SB:[Linux] Get Free Fragments (16, 0) SB:[Linux] Get Free Fragments (16, 0) SB: DSP command 0xd0 accepted SB: Pausing DMA transfer, 256 bytes left SB: Read 0x7e from DSP Write Buffer Status Register SB: DSP command 0xd4 accepted SB: Going to write 128 bytes SB:[Linux] Get Free Fragments IOCTL error (Broken pipe) SB:[Linux] Get Free Fragments IOCTL error (Broken pipe) SB: Going to write 128 bytes SB:[Linux] Get Free Fragments IOCTL error (Broken pipe) SB:[Linux] Get Free Fragments IOCTL error (Broken pipe) SB: Going to write 128 bytes Vedran ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
