/dev/dsp... how to target different dsp ?
i'm using xmms... and after doing a cvsup/rebuild from (8.0-release) to: FreeBSD elhdt.hoe 8.1-PRERELEASE FreeBSD 8.1-PRERELEASE #3: Sat Jun 12 15:39:04 PDT 2010 root@elhdt:/usr/obj/usr/src/sys/GENERIC i386 xmms nolonger works... and i think that problem is that 8.1-pre- release can now see additional sound devices that weren't seen before... my problem, is how do i get xmms working again (i think, rebind the /dev/dsp device?) how to bind /dev/dsp to a different beast.... elhdt# ls -l /dev/dsp crw-rw-rw- 1 root wheel 0, 117 Jun 18 13:07 /dev/dsp elhdt# ls -l /dev/dsp* crw-rw-rw- 1 root wheel 0, 111 Jun 17 15:41 /dev/dsp0.0 crw-rw-rw- 1 root wheel 0, 117 Jun 18 13:07 /dev/dsp0.1 crw-rw-rw- 1 root wheel 0, 90 Jun 17 15:41 /dev/dsp1.0 crw-rw-rw- 1 root wheel 0, 89 Jun 17 15:41 /dev/dsp2.0 crw-rw-rw- 1 root wheel 0, 88 Jun 17 15:41 /dev/dsp3.0 crw-rw-rw- 1 root wheel 0, 87 Jun 17 15:41 /dev/dsp4.0 hmm... clearly, devfs is synthesizing the response to the stat for /dev/dsp by the first ls -l, and the second shows that /dev/dsp is not really there, (the shell expansion of '*' doesn't see it) - so /dev/dsp is probably some sort of artificial virtual object synthesized by devfs. my problem is this. i want to bind to the dsp3.0 (pcm3) equivalent device, and not the pcm equivalent device (i think). how can i do this ? any help or suggestions would be appreciated! elhdt# cat /dev/sndstat FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386) Installed devices: pcm0: <HDA ATI R6xx HDMI PCM #0 HDMI> (play) default pcm1: <HDA Realtek ALC892 PCM #0 Analog> (play/rec) pcm2: <HDA Realtek ALC892 PCM #1 Analog> (play/rec) pcm3: <HDA Realtek ALC892 PCM #2 Digital> (play) pcm4: <HDA Realtek ALC892 PCM #3 Digital> (play)

man snd(4):
hw.snd.default_unit
Default sound card for systems with multiple sound cards. When
using devfs(5), the default device for /dev/dsp. Equivalent to a
symlink from /dev/dsp to /dev/dsp${hw.snd.default_unit}.
See also the manual page of snd_hda.

Apart from hw.snd.default_unit, you can also configure XMMS to use a
specific device:
Preferences
-> Audio I/O Plugins
-> Output Plugin: OSS Driver 1.2.11 [libOSS.so]
-> Configure
-> Devices

DSP t DSP Synchronization
What would be the easiest way to synchronize two DSPs using the TI 'C6701 programmable digital signal processor. Would it be easier to send a sinusoid from the transmitter end to the receiver and aknowledgement from the receiver to the transmitter or use a stream of known bits? Any help with algorithm, code or ideas would be appreciated. Thank you. I solved the same problem. Sinusoid did help but I used 5/6 frames for synchronization. Like Sinusoid+silence+silence+sinusoid+.. You can also use the more robust technique of known bits but it will increase ur processing during listening...

DSP parts with free dev software/cheap dev tools?
Hi - I'm looking at doing some DSP work (specifically, I'm working on an AHARS system). I've never worked with a DSP - but I understand them to essentially be a microcontroller with especially strong math abilities. Thus this seems like a perfect solution to my needs. Problem is - it seems most all DSPs require expensive dev software and hardware. I'm coming from the ARM and AVR world where software is free and programmers are inexpensive. Being a student - this transition is a bit unpleasant. Are there any inexpensive routs into the DSP world? I'm looking for a C compil...

Permissions in /dev/dsp
I have had problems on and off over the years with audio on Linux, but always hacked through it and made it work. Now I am trying to understand it. Now is the chance. I have two identical hardware systems with (supposedly) identical loads of Debian Sarge 3.1. Sound works just fine on one, but on the other when KDE loads it gets a "Device /dev/dsp can't be opened. Permission denied." And the error is correct because if I start a program needing sound (totem, XMMS) as su/root it works. So, I have a permission problem. Looking at the /dev/dsp on the working system I get... crw-rw---- 1 root audio 14, 3 2006-07-22 19:00 dsp On the non sound working box it is... crw-rw---- 1 root root, 3 2006-07-22 19:00 dsp So, the sound works with a group permission of audio 14, but only works as root with a group permission of root. But I don't see a group called audio 14 anywhere in my user/group utilities. In fact, I haven't been able to grep up a string of "audio 14" anywhere on the system. I have googled up lots of suggestions for a fix, but few if any have explanations. So, can anyone tell me what should have setup the "audio 14" group?

Even on command line, I cannot play any music. It looks like the Flash player in Firefox is locking the /dev/dsp as long as the browser is up.
