Other Parts Discussed in Thread: TLV320AIC3262, AM5728
Hello All ,
We are using audiocodec TLV320AIC3212 on our custom board based on TI AM5728 SOC TI SDK 6.03. We have ported and compiled TLV320AIC3262 driver to be used for 3212 device as suggested by TI experts. The driver and dts file is as attached. Kindly help resolve following issues :-
1. No Sound during VoIP Call : We are using a SIP client for VOIP application. No sound is heard when a VOIP call is made using it. Though both arecord and aplay applications are working fine for capturing and playing voice locally on the custom board respectively The SIP client sends and receives RTP packets with PCMU as the codec type.
The format of sound packets as seen by the driver is SNDRV_PCM_FMTBIT_S16_LE. This is supported by the driver. Are there any other parameter(s) that affect the handling of sound / PCM packets by the device ?
2. CONFIRMATION OF REGISTER MAP VALUES : Since TI doesn't provide the linux driver for 3212. The register map values are also not available. For our trials, values of register map has been copied from the i2cdump values of device. The attached code has the register map values used for our trials.
Could improper register map values be the reason for no voice during VoIP call? Could someone guide in this direction or provide the proper register map for TLV320AIC3212.
