Comment 39 for bug 253422

I don't have spdif either, but I've been using this workaround for more than a year now (since Gutsy), and everything worked fine with mic, headphones.
And another thing, I didn't choose targa-2ch-dig because I found this bug report - it didn't exist back then - I tried the different options at ALSA-Configuration.txt for ALC883, and this was the only one that made things work back then. One detail, the options available in ALSA-Configuration.txt were a lot less one year ago (something like 6 or 7, now there are 21). So it may be that there is some other option that makes it all work.
