That is okay, I can ask our QA to do some test to the alsa update
with our SB700 platform. But
1. Which items do you want to be tested? HD audio and HDMI audio?
2. From which ISO release this update will be included? RHEL4.8 Beta?
We can test the RHEL4.8 release if it will come soon.

Thanks

The whole snd-hda-intel driver (HD + HDMI audio) is affected. I would like just
to get some preliminary test results before inclusion to RHEL 4.8 kernel.
Please, just do only a really quick test for the moment (install hdaUpdate3
kernel in comment#3 and try basic audio functionality). Thanks.

OK, our QA will do a basic test on our platform.

I've done some basic test for HDA&HDMI. All HDA functions seems to be good so far.
But there is some command line changing when aplay audio file via HDMI.

aplay -Dhw:1 xxx.wav(HDMI device is on cards 1) ----- works in RHEL4U7 RC,
failed with this new patch, error message as below:
>ALSA lib pcm_hw.c:1155:(snd_pcm_hw_open) open /dev/snd/pcmC1D0p failed: No such
>file or directory
>aplay: main:508: audio open error: No such file or directory

aplay -Dhw:1,3 xxx.wav ----- works well with this new patch.

Yes, PCM device indexes were changed, because we tried to solve other problem:

    [ALSA] hda-intel - Fix PCM device number assignment

    In the current scheme, PCM device numbers are assigned incrementally
    in the order of codecs.  This causes problems when the codec number
    is irregular, e.g. codec #0 for HDMI and codec #1 for analog.  Then
    the HDMI becomes the first PCM, which is picked up as the default
    output device.  Unfortuantely this doesn't work well with normal
    setups.

    This patch introduced the fixed device numbers for the PCM types,
    namely, analog, SPDIF, HDMI and modem.  The PCM devices are assigned
    according to the corresponding PCM type.  After this patch, HDMI will
    be always assigned to PCM #3, SPDIF to PCM #1, and the first analog
    to PCM #0, etc.

Thank you for testing.
