-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Somebody in the thread at some point said: | Is there any way to switch the audio path to some file output? | i.e. can I (potentially) record "buzz" without an active GSM connection | ( while irradiating the phone from an external HF source ) | would be cheaper and easier to set up that way.
Werner pointed out yesterday to a guy asking the same thing that /usr/share/openmoko/scenarios/capturehandset.state should be the thing. As far as I know, nobody yet tested this with buzz and so confirmed that the effective buzz problem actually comes at the MIC inputs to WM8753. | <someone> |> Well maybe luckily we *might* eventually find a magic place for a (33pF) C |> somewhere near Wolfson chip, to rework GTA02 out in the field this way. |> Anyway I'd rather expect this magic fix to be found by try and error, rather |> than probing on a setup that's completely changed by mere applying a probe to |> it. | | Could someone with the device open place 100Ohm resistor in series with | 3/4pF from the mic line to GND and test it?

I don't have gerber layer data, but the bead was placed in series with headphone jack p4, it should be possible to try. But I don't have 3.. 4 pF caps lying around, I order some for tomorrow. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkjXqg8ACgkQOjLpvpq7dMoLSACbBjcDn+Vci3vOT+Yk06+PIIv9 gGMAnRL+N4hGTJlqXDJba4ZEBnFpZhmm =KP6t -----END PGP SIGNATURE----- _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
