| So, what is required to make the dsp-device delive audio-data? | | Q: The hardware does support this, right? Yeah. | Q: Is it a audio-driver problem, e.g. the alsa-device-driver for the chip | doesnt support audio capturing? | | Q: Is it a problem with my mixer settings? If so, which are the correct | mixer settings? I can't give you a straight answer on what to do, but here is the situation around it. The normal audio routing for the microphone inside the WM8753 codec is to bring it in on "MIC2" port and then send it via an "analogue path" around some scalers and mixers and switches and send it back out again on MONO1 / MONO2 to the GSM chip. In short it doesn't get delivered to the ADC in the Wolfson where you can pull it as normal PCM. You can see it here: http://wiki.openmoko.org/images/2/2c/WM8753_BlockDiagram_GSM_handset.png If the PGA and mux are configured, it should work OK. One last consideration, the Mic is OFF unless you enabled MICBIAS signal to power it. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkiPH/8ACgkQOjLpvpq7dMp3hgCgi4EvcI7gCEKekwYzytpNl4Bh YdEAniUhQs3bUGOPoPim5Zt+H2PTjDdx =TMnZ -----END PGP SIGNATURE----- _______________________________________________ support mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/support
