[alsa-devel] [REPOST] opti93x: conversion to use cs4231 library
by Krzysztof Helt 07 Feb '08

07 Feb '08

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> This patch converts the Opti93x driver to use the cs4231 library instead of just duplicating the code. Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- This patch requires the patch which adds opti93x support to the cs4231 library. The patch is done against the current alsa hg tree, which means that the optin92x-ad1848.c file must be downloaded from the hg tree (it is newer by one patch than the file from 2.6.24-rc8-mm1 kernel).

[alsa-devel] Hg update problems
by Eliot Blennerhassett 07 Feb '08

07 Feb '08

Hi Takashi, Wierd, I can see your checkin in a browser at http://hg.alsa-project.org/alsa-driver/ 14 hours ago: asihpi version 3.09.09 changeset 3506: e600ecb8fbd7 tag: tip author: tiwai Also I see it in a clean clone of the repo. but hg pull on my original repo still gets nothing same as before, head is out of date - details: eliot@zaphod:~/src/alsahg/alsa-driver$ hg -v --debug heads changeset: 3507:86adcd0d6d849d5f8d41448d3cd4d1a8660d6214 tag: tip description: Added tag v1.0.16rc2 for changeset 1dc44ca35555 Tracing (strace) further I see that Hg queries the repository like this http://hg.alsa-project.org/alsa-driver/?cmd=heads and gets back 86adcd0d6d849d5f8d41448d3cd4d1a8660d6214 So the remote repo is telling me that my local is up to date, even though the web interface shows more recent tip. Very wierd... Anyone else see this or shed any light on it? -- Eliot

[alsa-devel] DSP2000 Midi In - Not a correct fix??
by Alan Horstmann 06 Feb '08

06 Feb '08

I think it is time to post my investigations so far... re: Hoontech DSP2000 Midi In non-functional see : https://bugtrack.alsa-project.org/alsa-bug/view.php?id=55 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1161 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1846 I missed a fix patch in March 07 for this as it was put on a later duplicate of the bug report I had contributed to. However I noticed JK closing -> resolved these in Jan 08, so tried the patch: http://hg.alsa-project.org/alsa-kernel/rev/319688a93b6e From my testing, it seems the only part necessary is:- - for (box = 0; box < 4; box++) { + for (box = 0; box < 1; box++) { as it is successful without the rest. However I feel this is not really a correct fix, preventing use of multiple boxes in code that originally allowed it. The code is a little strange and has taken me a while to approximately grasp. What seems to be going wrong is that when a second box is configured (ie box = 1) the function snd_ice1712_stdsp24_box_midi(...) switches the midi input off box[0]. If box[1] has ICE1712_STDSP24_BOX_MIDI1 set in it's config, then midi in and out can work on box[1] instead of box[0], but otherwise it is just stopped on box[0]. After many hours/days of tests I still can't propose a definite way to fix this function to provide correct configuration to all 4 allowed boxes, as I really don't understand why the code does all the gpio writes that it does. Unfortunately I do not have any circuit information either. In some way it seems to be latching some of the configuration data, but not all. Clemens, can you remember anything about this change: http://hg.alsa-project.org/alsa-kernel/rev/a42043505e46 -was it someone else's patch or did you work on this? I am hoping that someone can contribute enough of an idea about this to help formulate a proper fix. Unfortunately, as the bugs are closed, I can not continue the discussions there. Alan

[alsa-devel] ALC268 (no sound)
by Marco Schuster 06 Feb '08

06 Feb '08

Hi all, maybe this topic is a bit outdated, but still, when using the current hg code of the kernel module together with 2.6.24 (stable), I can't get any sound :( Do I have also to upgrade the ALSA libs and programs? Marco

Hi, unfortunately it didn't solve the issue. Same problem: no audio signal can be recorded. I provided all the information at http://pastebin.ca/886740 If we can't solve the issue this way, maybe we could lend you one of our cards ? Greeting, Toast

[alsa-devel] Intel ICH Modem init fails for laptop built-in SiS modem
by Richard Kennedy 03 Feb '08

03 Feb '08

My JVC mininote laptop has an inbuilt SiS modem 00:01.6 Modem [0703]: Silicon Integrated Systems [SiS] AC'97 Modem Controller [1039:7013] (rev a0) which is detected by the snd-intel8x0m driver but it always fails to initialise and spams the log file :- kernel: codec_semaphore: semaphore is not ready [0x1][0x1300] kernel:last message repeated 2 times kernel: codec_semaphore: semaphore is not ready [0x1][0x300] kernel:last message repeated 431 times kernel: AC'97 1 does not respond - RESET kernel: codec_semaphore: semaphore is not ready [0x1][0x300] kernel: codec_semaphore: semaphore is not ready [0x1][0x300] kernel: AC'97 1 access is not valid [0xffffffff], removing mixer. kernel: Unable to initialize codec #1 kernel: ACPI: PCI interrupt for device 0000:00:01.6 disabled kernel: Intel ICH Modem: probe of 0000:00:01.6 failed with error -5 I never use the modem so I blacklisted the snd-intel8x0m module in modprobe.conf just to make the messages go away. I'm currently running the fedora 2.6.23 kernel but it has been broken for a long time. Is this fixable? or shall I just go on ignoring it ;) ? cheers Richard

[alsa-devel] underruns and strange code in pcm_rate.c (and patch)
by Stas Sergeev 01 Feb '08

01 Feb '08

Hi. I spent 4 week-ends debugging the constant underruns and lock-ups with the libao-based programs. Now I've finally tracked the problem to some strange code in pcm_rate.c, namely snd_pcm_rate_poll_descriptors(). I am not sure what was the reason behind altering the "avail_min" every time. Looks like some heuristic was intended, say "see what amount of fragment part was written now, and make sure that amount of free space will be available next time, after poll". Whatever, this code gives underruns. It can increase avail_min by almost period_size. libao sets avail_min==period_size, so we can end up with avail_min==period_size*2. libao sets buffer_size==stop_threshold==period_size*2. So we end up with avail_min~=stop_threshold, which gives underruns. Since I don't know how this code was indended to work, I just removed it, and everything works perfectly now (also had to patch libao to check the returned rate). The patch is attached, any comments?

[alsa-devel] es1938 - patch trying to improve capture hw pointer reads
by Hermann Lauer 01 Feb '08

01 Feb '08

Hello, with the Solo1 (es1938) I got a lot of xrun's during capture on my machine. Tracing that down it seems to be comming from reading ocassionaly bad hw pointers from the chip. Appended is a patch against linux-2.6.23.12 which uses more checking to avoid that false pointer reads. Failed reads are giving back the last good value read instead of spinning in a tight loop, which seems more appropriate to me in an interrupt. I think I saw this trick used in another driver. On my machine xruns seems to be gone with that patch. If anybody is interested, mmaped capture seems also to be doable with some tricks, still testing this...
