Seigo http://people.FreeBSD.org/~tanimura/patches/newmidi/2ndbuf-19991227.diff.gz Great, the sound drivers are working very nicely on my ESS 1868. Does pcm support SoundBlaster WavEffects? Hopefully, nobody will do anything to break the sound drivers (although it may happen). I think I'll make a backup of my /sys/dev source code tree just in case. ;-) - Donn To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

On Fri, 24 Dec 1999 10:39:31 +0900, Seigo Tanimura [EMAIL PROTECTED] said: Seigo players. My sound cards are SB32, SB64 and CS461x, so the problem is Seigo likely to be in channel.c or dsp.c. OK, here is the result of my investigation on RealPlayer 5.0: RealPlayer 5.0 is an ill-behaving application in two points. First, it passes a size of 16 to SNDCTL_DSP_SETFRAGMENT. This size is obviously too small to buffer pcm data. Second, RealPlayer 5.0 often attempts to write larger pcm data than the block size of the secondary buffer. The result is to write only a part of pcm data ending up with an error, and make polling really weird. AFAIK these problems are fixed in RealPlayer G2. The following fixes are somewhat klutzy, but seem to work: - If a device is in nonblocking mode, adapt the block size to the pcm data to write. - Poll the remaining size to write, rather than that of free space. These fixes are included in: http://people.freebsd.org/~tanimura/patches/newmidi/2ndbuf-19991225.diff.gz -- Seigo Tanimura [EMAIL PROTECTED] [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

On Mon, 20 Dec 1999 13:44:02 +0900, Seigo Tanimura [EMAIL PROTECTED] said: Seigo If you have a trouble playing pcm with some applications, could you Seigo please try the patch attached below? The patch does the following things: Seigo - All ioctl(2)s go to see the secondary buffer(if I have forget nothing). Seigo - chn_setblocksize() changes the size of the secondary buffer. Seigo - chn_mmap() maps the secondary buffer. Seigo - chn_poll() invokes DMA. Seigo - chn_wrintr() performs DMA emulation for pcm devices with no DMA Seigo functionality(requested by nyan). Seigo With the patch, snes9x(w/-r 7) and RealPlayer G2 for Linux worked fine. Seigo The range of blksz in chn_setblocksize() may need further tuning... The patch has been updated slightly. Now snes9x works with any pcm quality you like. The new features are: - SNDCTL_DSP_SETFRAGMENT handles the count correctly. - GETI/OSPACE returns the number of fragments. - DMA transfer keeps running upon underrun. Some DSPs seem to end up with an unpredictable result if the DMA gets stopped followed by immediate restart. This revokes the change in sys/dev/sound/pcm/channel.c rev 1.12. 2ndbuf-19991223.diff.gz -- Seigo Tanimura [EMAIL PROTECTED] [EMAIL PROTECTED]
