| 02:19.38 | jfro | just turned off glx driver |

| 22:00.40 | pahartik | johill: ALSA snd_powermac Snapper |
| 22:01.03 | johill | heh finally on at the same time |
| 22:01.20 | johill | ok so it's not my problem I guess if you don't use snd-aoa ;) |
| 22:02.39 | pahartik | johill: Those modules get loaded too, but do not detect any hardware |
| 22:04.33 | johill | yeah, they only detect hw if you have a layout-id in the devtree |
| 22:04.42 | johill | the i2sbus is still detected but it doesn't claim it |
| 22:05.47 | pahartik | johill: I have tried Linux 2.6.17 and Linux 2.6.20 versions |
| 22:06.21 | johill | does it make a difference? |
| 22:07.16 | pahartik | johill: No difference on ALSA AOA driver |
| 22:07.29 | johill | no I mean wrt. your problem |
| 22:07.40 | johill | maybe you mentioned that before but I forgot :) |
| 22:09.18 | pahartik | johill: No, it sounds equally quiet... With mixer set to full audio can be barely heard, with lots of "clipping" |
| 22:09.29 | johill | hm |
| 22:09.36 | johill | sounds like the i2s bus is programmed wrong |
| 22:09.53 | johill | like I had when I programmed the bus to 32-bit but in the wrong byte-order |
| 22:10.00 | johill | the codec is 24-bit |
| 22:10.14 | johill | so I ended up having sound in bytes 1-3 but the codec reading bytes 2-4 |
| 22:12.01 | pahartik | johill: That could explain it |
| 22:12.56 | johill | that'll be hard to debug though |
| 22:12.57 | johill | but first check if it's actually running in 24-bit mode |
| 22:12.57 | johill | actually |
| 22:13.03 | johill | snd-powermac doesn't reprogram the i2s bus at all |
| 22:13.18 | johill | do you have a startup "bong" sound? |
| 22:13.49 | pahartik | johill: That is loud enough to be irritating |
| 22:14.43 | johill | hm |
| 22:14.47 | johill | so there it's fine |
| 22:14.52 | johill | and snd-powermac doesn't touch the i2s bus |
| 22:15.10 | johill | snd-aoa-i2sbus also shouldn't |
| 22:15.15 | johill | different problem then |
| 22:15.26 | johill | more likely the codec itself |
| 22:15.33 | johill | maybe your codec has a master and a pcm control |
| 22:15.37 | johill | and master isn't visible or something |
| 22:15.49 | johill | I get clipped sound on my powerbook if I turn pcm to max, no matter where master is set |
| 22:16.04 | johill | even if master is really quite pcm at max causes clipping |
| 22:16.09 | johill | what codec does that thing have? |
| 22:16.31 | pahartik | johill: I do not know? |
| 22:17.00 | johill | ok |
| 22:18.31 | johill | I'm swaying between helping you out and not wanting to open that can of worms ;) |
| 22:18.46 | johill | I suppose that to really fix it I'd probably need to put support for it into snd-aoa |
| 22:19.03 | johill | snd-powermac code is really not something I want to see again |
| 23:31.29 | pahartik | johill: Would it help if you had access to that system? |
| 23:32.14 | johill | not sure |
| 23:32.20 | johill | maybe I could figure out what codec it has |
| 23:32.33 | johill | or just mail me the device-tree (tar-ball of /proc/device-tree) |
