Hello,

I am trying to add alsa feature to Android on hdk7108 (which is sh4 architecture, not arm).

Basically on non android linux platform ,i.e STLinux-2.4, the driver and alsa-libs and alsa-utils works with the following test command: --------------------------- #aplay -v -t raw -D hw:1,0 -c 2 -r 32000 -f S16_BE /32K_16Bit_Stereo.pcm" ---------------------------

But when working on Android platform, because the alsa-lib/alsa-utils are different from STLinux-2.4, so we ask someone the two packages from a arm platform. and compilation ok. but during run alsa_aplay, the following error occurred:

----------------------------------- #/system/bin/alsa_aplay -v -t raw -D hw:1,0 -c 2 -r 32000 -f S16_BE /32K_16Bit_Stereo.pcm

ALSA lib vendor/STMicroelectronics/hdk7108/alsa/alsa-lib/src/confmisc.c:137:(snd_config_get_bool) confmisc.c in func snd_config_get_bool line 137 Invalid type for nonblock

ALSA lib vendor/STMicroelectronics/hdk7108/alsa/alsa-lib/src/pcm/pcm_hw.c:1417:(_snd_pcm_hw_open) Invalid type for subdevice aplay: main:656: in aplay.c func main line 656 audio open error: Invalid argument aplay/main.c in func main line 452 alsa-lib/src/pcm/pcm.c func snd_pcm_open line 2242 after call snd_config_update(), err=1 ----------------------------------

looks like alsa configuration issue. I noticed that on STLinux-2.4 platform, the alsa-libs is 1.0.21a and on android platform, it is 1.0.16, can this be a issue?

or configuration file wrong or else? how to debug this?

Thanks you very much! Houxiang
