Hi all, I am trying to run alsa sound card driver for ES1371 chip on a real time operating system. I have successfully written the PCI driver on my platforam and able to read/write most of the PCI IO mapped control registers of ES1371. The problem is regarding the initialization of SRC( Sample Rate Converter). The sound card has a control register interface to read-write the SRC RAM. I am not able to write or read the SRC RAM. Can any one of you guys help me regarding the SRC intialization. I have done all the things which are written in the function static int __init snd_ensoniq_create in card-ens1370.c I tried to clear the bit SRC-DISABLE to enable the Sample Rate Converter. But if i read back the value of Sample Rate Converter Interface register, i get the PowerOnReset value which is 1. So i think i am not even able to write the interface register. What could be the problem? Thanks in advance! -Neeraj _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
