Description Yang, Libin 2007-10-25 08:43:35 UTC 
Description of problem:
The Audio driver does not work well on Trevally board(RS690 + SB700) which uses
AD1984 as its HDAudio codec chip/PCM device. 

The symptom is:

The audio is abnormal, when a ".wav" file is being played, usually there
are many(10 or more or endless) abnormal loops of middle PART of its audio,
which make the audio turn out to be NOISE, here are some examples:

[root@localhost ~]# aplay /usr/share/sounds/startup3.wav 
Playing WAVE '/usr/share/sounds/startup3.wav' : Signed 16 bit Little Endian, 
Rate 44100 Hz, Stereo
aplay: pcm_write:1115: write error: Input/output error

[root@localhost ~]# aplay XP_startup.wav 
Playing WAVE 'XP_startup.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, 
Stereo
aplay: pcm_write:1115: write error: Input/output error

[root@localhost ~]# aplay /usr/share/sounds/KDE_Startup.wav 
Playing WAVE '/usr/share/sounds/KDE_Startup.wav' : Signed 16 bit Little 
Endian, Rate 22050 Hz, Mono
(comment by Shane: endless loop playing of KDE_Startup.wav)


Additional info:

Sound card seems can be recognized correctly:
[root@localhost ~]# aplay -l

Comment 5 Yang, Libin 2008-01-03 02:42:18 UTC 
I have uploaded 2 patches for this bug. The two patches can fix this bug. 
Please check.
Comment 6 Bhavna Sarathy 2008-01-03 15:06:51 UTC 
These patches are for R4.7.  Russ, please add to 4.7 master bug tracker.

Libin, is the Intel fix necessary for the Trevally board to work?
Comment 7 Yang, Libin 2008-01-04 01:30:42 UTC 
Yes, the two patches are both needed. 
The patch "update the position_fix" is the root cause. This such bug has already
been fixed by ALSA long before. Actually you will find the code
"azx_dev->period_intr++;" in hda_intel.patch is included in the current ALSA
1.0.15. This code is missed when back porting.
Comment 8 Brian Maly 2008-02-15 15:38:46 UTC 
Devel ACK for 4.7 on condition that ALSA 1.0.15 works properly on this hardware.
The assumption here is that it does.
Comment 9 RHEL Program Management 2008-02-28 20:09:31 UTC
