Sound driver (OSS)

[dave900_fr]

Hello,

I know this is an unsual request, but I really like freenas and the only thing missing for me so far is how to recognize a sound card (so musicpd can output audio on it). I don't want to have another computer just for this.

Anyone has achieved this so far? It seems that you need kernel sources to build oss package. But I would appreciate some help on how to do this.
For information, I have freenas 9.1.1. I am fine with upgrading to 9.2 in order to get the new jail templates (debian, ubuntu...) if this can help.

Cheers,
David

I'm not sure about sound drivers but I'm guessing this could be accomplished in a jail..

Well yes this is what I was hoping for. So far I can't install oss package in a jail. This is the output I have

Code:

I guess this is because the jail cannot have access to the audio device or something like that since it is not installed in freenas...
Any ideas?

Um... FreeNAS servers are supposed to be file servers and not servers to play music on. As such, I don't believe you can get this to work without significant rework and recompiling of FreeNAS.

People ask for audio support once in a blue moon and the answer is simple... FreeNAS does not and will never include audio drivers. It is meant to be a file server appliance and that is all. The more stuff you add the more likely of there being problems. File servers should be as stable as possible which is why FreeNAS is stripped down to only the most basic stuff.

If this is a deal breaker then FreeNAS is clearly not for you.

What command are you using to install into the jail?

To get sound working in the jail, you need to configure devfs, like seen in this post.

 

[dave900_fr]

Well, I tried to follow the instructions from the post in a portjail in Freenas 9.2 but without success, still the same error. I am probably doing something wrong in the configuration but don't know what...
I have jail named "freebsd" so I have written this in /etc/devfs.rules (freenas system):

Code:

# Devices usually found in a desktop jail.
#
[devfsrules_freebsd_jail=5]
add include $devfsrules_hide_all
add include $devfsrules_unhide_basic
add include $devfsrules_unhide_login
add path 'mixer*' unhide
add path 'dsp*' unhide
add path 'dri' unhide
add path 'dri/card0' unhide

Then inside the jail, i.e., /mnt/test/freebsd/etc/rc.conf, I have the following:

Code:

portmap_enable="NO"
sshd_enable="NO"
sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"
hostname="freebsd"
devfs_enable="YES"
devfs_system_ruleset="devfsrules_common"
jail_freebsd_devfs_ruleset="devfsrules_freebsd_jail"

Any ideas?

Thanks,
David

And I forgot, I am using this command within the jail to install oss:
pkg_add oss-freebsd9-v4.2-2008-amd64.tbz

It will not work even with devfs configured in the jail. There are no snd_ modules included with FreeNAS, so there's no /dev/dsp, no /dev/sndstat. If you want sound you need to fetch the FreeNAS source tree and build a kernel that includes the sound drivers (or just build the sound kernel modules).

Ok, thanks, that explains it!
