Hi,Misa
1.
I have wm8987 driver for my board,my kernel version is 2.6.24.7
supplied by the board vendor ,and I have porting the android driver to
it,before porting the alsa ,I can run eclair well ,wifi ,phone module
etc can work well.
and here are my .config file in the kernel root dir
1313 # System on Chip audio support
1314 #
1315 CONFIG_SND_SOC=y
1316 CONFIG_SND_S3C_SOC=y
1317
1318 #
1319 # SoC Audio for the Samsung S3C
1320 #
1321 CONFIG_SND_S3C6410_SOC_I2S_V32=y
1322 # CONFIG_SND_S3C64XX_SOC_SMDK6410_WM9713 is not set
1323 # CONFIG_SND_S3C6410_SOC_AC97 is not set
1324 # CONFIG_SND_S3C6410_SOC_SMDK6410_WM8580 is not set
1325 CONFIG_SND_S3C64XX_SOC_SMDK6410_WM8987=y
1326 CONFIG_AUDIO_CODEC_PROCFS=y
1327 # CONFIG_SND_S3C64XX_SOC_SMDK6410_WM8990 is not set
1328 CONFIG_SND_SOC_WM8987=y
1329
1330 #
1331 # Open Sound System
1332 #
1333 # CONFIG_SOUND_PRIME is not set
1334 CONFIG_HID_SUPPORT=y
1335 CONFIG_HID=y
1336 CONFIG_HID_DEBUG=y
1337 CONFIG_HIDRAW=y
And here are the kernel bootup info:
Advanced Linux Sound Architecture Driver Version 1.0.15 (Tue Nov 20
19:16:42 2007 UTC).
ASoC version 0.13.1
WM8987: Audio Codec Driver v0.12
asoc: WM8987 <-> s3c-i2s mapping ok
Proc-FS interface for audio codec
ALSA device list:
#0: smdk6400 (WM8987)
2. open("/dev/snd/pcmC0D0p", O_RDWR|O_NONBLOCK|O_ASYNC|O_LARGEFILE)
= 11
I don't agree with you ,11 is not the error No.The open() function
return the file description of the file it opened,if it failed to
open ,it will return -1.
3. Also you didn't mention adding sound symlinks in init.rc
Just now I have add the symlink in init.rc .But the problem remain.
Thank you~
