Playing Audio CDs with no sound output.

S

shuxuef

Hello, there.

I am a newbie who installed FreeeBSD 7.2-Release on a HP V3919TU laptop with Microsoft Vista several days ago. I don't know much about Unix and FreeBSD, so I decided to learn. The FreeBSD was installed on a primary partition, with some warning about the geometry or something while being installed. After the installation, I built and installed a new kernel loading the sound module and snd_hda for my sound card. I read the related sections of the handbook and the manual pages for many times, and used google and the FreeBSD website, but I can't still fix the problems.

There are many devices I couldn't use right now. But all the devices are working really well using the Vista.

One of the problems is: I couldn't play audio CD using any of cdplay, cdcontrol, KCD, mplayer, etc; using cdplay or cdcontrol, I can tell the CD's running, but no sound output; but I can play any .mp3, .wav files, and cdd2wav works very well for the ripping. Data CDs could be read correctly too. And I can also use burncd to burn a CD. But under no circumstance could I use my headphones; i.e. I can only use the built-in speaker.

Under Vista, the sound device is labeled as "Conexant High Definition SmartAudio 221"; the DVD/CD-ROM device is labeled as "Optiarc DVD RW AD-7560A ATA Device".

The output of the verbose /dev/sndstat is the attached sound.txt.

The output of mixer is



Mixer vol is currently set to 78:78
Mixer pcm is currently set to 100:100
Mixer speaker is currently set to 75:75
Mixer mic is currently set to 70:70
Mixer rec is currently set to 0:0
Mixer ogain is currently set to 50:50
Recording source: mic


And it doesn't work if I change the values of them to the maxima.

And I tried to set the hw.snd.default_unit to all possible value, I still couldn't use the headphones and play CDs.


Thanks a lot in advance!

Sure!
For pciconf, please see the pciout.txt, and for the sndstat, please see sound.txt. (I don't know how to insert text inside a framed box with scroll bars... sorry)

Thanks!

mixer output doesnt list cd so you cant play cd directly via cdcontrol.
If mplayer is build with cdda support, you could play cd just fine.

Unfourtunately I cant help you here because you did not provide verbose dmesg output with hdac0 lines.
Better and faster help you may get from freebsd-multimedia@ mailing list, and in its archives I believe
there are already working solutions for if not same but very similar problems.

Thank you richardpl. I attached it here, if you are still interested in. And I also searched the archives before posting my problem, but I couldn't find a similar one ...

For the part about hdac, please see hdac.txt (the whole dmesg.boot is too big to be attached....)


Thanks!

That's what I thought. And some error message keeps appearing on tty0 as well as the dmesg.boot file; I wonder if it has something to do with the CD pin (or whatever the name is):

Thanks again. And sorry for the mess.

One of the problems is: I couldn't play audio CD
Click to expand...

I would bet $100 that your laptop doesn't have a physical wire connection between DVD/CD-ROM and your audio card. In order for CD to be played on BSDs generally speaking audio card must be connected to CD-ROM with a wire.

On OpenBSD the solution would be very simple. You would play CD through motherboard as on Windows.

Code: 
cdio cdplay


I am not aware if that is possible on FreeBSD.
Very simple option for FreeBSD would be to write a script which would rip the song from CD play it and then erase it.

I never bothered to learn that UAA kind of thing and don't have time ....
Look in snd_hda(4) for possible device.hints configuration via /boot/loader.conf
Click to expand...

On the manual page of snd_hda, it is said that :
Using device.hints(5) it is possible to modify the configuration of the existing pins, allowing a broad range of different audio setups.
Click to expand...
I don't think all the devices are correctly detected in my case. So I don't know how to use the device.hints(5) :(

By the way, how do I learn to read the dmesg.boot file? Any books or web resources?

Hmm...I dare not bet... Any suggestion on how to check it? Thanks!:)

Try to rip songs from the CD to the HDD and to play them. If it works I am almost 99% sure you do not have a wire between DVD/CD-ROM and the audio card. On OpenBSD which I use that would look something like

Code: 
cdio rip 
cat track1.wav > /dev/sound

Yes, it works, as I said at first.
So I guess I can only play CDs by ripping them then; there would be some legality issue, though.
 
Don't listen Oko. He really do not know what he is talking about.

Here is how I play CD with mplayer:

% mplayer cdda://

On OpenBSD cdio is just improved cdcontrol, so it is possible to play CD through motherboard and not only directly to sound card.

Maybe one day FreeBSD will stole it back from OpenBSD.
It should not be problematic to port it ....

I suppose in order for mplayer to support the cdda format, you need to turn on the CDPARANOIA option to use cdparanoia, because that's what I did; and presumably the data extracted is piped to the output via the sound card... (just guessing ) So Oko is right in some sense --- you still need to rip it, although the definition of `ripping' is not so clear. :)
 
Just out of curiosity, is the little analog sound cable from the CD-ROM drive connected to the sound card? If not, you will not be able to play audio CDs using any of the "normal"/analog means (ie, just open it in an audio app). Without that cable, you have to resort to reading the CD as digital data, and converting it to audio.

I couldn't check it directly; but as Oko said, it is not the case, since the ripping is possible.

By the way, another quick question: does any know how to set up the headphones? Mine's not working. I am learning the handbook page by page, hopefully I will find it out someday; but it would be very helpful if someone can give me a hint. Thanks.

Actually, setting hw.snd.default_unit to be 1 works for me; I just don't why it didn't work when I tried it before.

So then by putting the headphones and the speaker in the same association, with the seq of headphones being 15, the auto-mute function also can be enabled. Now they are working very well!:) Problem solved then.
