snd-powermac in CVS busted?

snd-powermac in CVS busted?

[Josh Huber]

I've finally decided to switch from using OSS to ALSA, and everything
works great, except I don't get any sound output!  I'm sending this to
the devel list since I'm dealing with the CVS version of the driver.

Using alsamixer I tried setting the Master channel at 100% as well as
the "PC Speaker" channel at 100%.

The detection of headphones seems to work, since the pc speaker
channel gets auto-muted when headphones are plugged in. (but, still no
sound is played out the headphone jack.

Using alsaplayer works great, and the visual plugins show that sound
should be playing. xmms works with the OSS compatibility driver as
well.

I built the drivers with --enable-debug=full, but I don't see any
additional kernel messages from ALSA.

I'm running Debian unstable (sid), on a Powerbook G3 Lombard, which
has the AWACS sound chip.  I'm using the CVS version of the drivers,
and the packages for libasound (0.9.0rc3), alsa-utils (0.9.0rc3), and
alsaplayer (0.99.71).

Any ideas?  What can I do to further debug this problem?

Here's the output from amixer:

I've seen mention of people wondering where the PCM slider is in the
mixer, does this have anything to do with my problem? (perhaps?)  Am I
supposed to have a PCM channel?

Thanks in advance for the help,

could you change 'Mic Boost' once to another value?
i got reports that this affects even on the pcm playback...


ciao,

Okay, thanks.  I'll try this tonight after I get home from work!

It works after tweaking the Mic Boot settings, but there are some
issues unfortunately :(

Things are close though!

1) The OSS emulation interface seems to be working very well -- xmms
   functions perfectly with it using the OSS output plugin.
2) alsaplayer generates static unless you turn the volume slider
   almost to 0, and even then the audio contains static during the
   loud parts of the music.
3) the xmms alsa output plugin always generates static
4) terminatorX does NOT generate static, and the audio sounds great...

I suspect there are some endian issues, eh? :)  I wonder why the oss
emulation layer works fine though.

As a review, I'm running the CVS versions of all the libraries and
tools now as well as the drivers:

i2c-core               14568   0 [snd-powermac]

All the fun applictions use the ALSA interface, which is what I really
want to start using.

There was an endianess issue with alsa-xmms but it was corrected today.
Try updating your sources from CVS.
