[alsa-devel] Keep getting underruns
by Barclay, Bruce 31 Mar '08

Not sure what causes this in the Alsa framework. I only get one at the beginning of the song but not sure how and why I get it. Does it have to do with the return of my pointer callback or because I call snd_period_elapsed in my interrupt routine too soon. Any ideas or docs to read? Bruce

[alsa-devel] M-Audio Revolution 7.1 sound card causing crash on Alpha
by Michael Cree 31 Mar '08

31 Mar '08

I recently installed a M-Audio Revolution 7.1 sound card into DEC/Compaq Alpha XP1000, and it is causing crashes and complete lock ups of the computer when I attempt to play sound through the sound card. Since this is my main computer I shifted the card to a DEC Alpha PWS500au and it causes the same lock ups there, and in one case a kernel oops made it into the system log (listed below). The crashes occur when any application plays sound through the card. The first instance of running an application (such as aplay or speaker-test) after bootup succeeds; it's the second time one runs such an application that the system crashes. I am using the ice1724 alsa driver. The sound card works fine - I've verified it on a MS Windows machine. It also worked fine when I installed it in a x86_64 machine running Debian testing. This seems to be a bug possibly specific to the Alpha architecture. Any ideas as to the problem? Any suggestions as to effective debugging? I turned on the debug options for alsa in the kernel config and re-compiled, but couldn't find any alsa debugging information in any of the system logs. Basic system details follow: DEC Alpha PWS500au with a 600MHz Alpha EV56 cpu. Debian GNU/Linux - up to date testing (Lenny) distribution. 2.6.24.3 verbatim kernel self-compiled and alsa as provided in that kernel. The kernel oops from one crash is as follows: Mar 4 22:04:04 aleph kernel: Kernel bug at mm/mmap.c:2054 Mar 4 22:04:04 aleph kernel: speaker-test(1885): Kernel Bug 1 Mar 4 22:04:04 aleph kernel: pc = [<fffffc000036bec4>] ra = [<fffffc000036be88>] ps = 0000 Not tainted Mar 4 22:04:04 aleph kernel: pc is at exit_mmap+0x134/0x150 Mar 4 22:04:04 aleph kernel: ra is at exit_mmap+0xf8/0x150 Mar 4 22:04:04 aleph kernel: v0 = 0000000000000000 t0 = 0000000000000003 t1 = 0000000000000040 Mar 4 22:04:04 aleph kernel: t2 = 000000000000003f t3 = fffffc002300c5f8 t4 = 0000000000000001 Mar 4 22:04:04 aleph kernel: t5 = fffffc00001da000 t6 = 0000000000000000 t7 = fffffc00212dc000 Mar 4 22:04:04 aleph kernel: a0 = 0000000000000000 a1 = fffffc002300c400 a2 = 0000000000000000 Mar 4 22:04:04 aleph kernel: a3 = 0000000000000000 a4 = 0000000000000000 a5 = 0000000000000000 Mar 4 22:04:04 aleph kernel: t8 = 0000000000000000 t9 = 0000000d1bc1e51d t10= 1a00000000000000 Mar 4 22:04:04 aleph kernel: t11= 0000000000002000 pv = fffffc000037b3d0 at = 0000000000000003 Mar 4 22:04:04 aleph kernel: gp = fffffc00006fb518 sp = fffffc00212dfbe8 Mar 4 22:04:04 aleph kernel: Trace: Mar 4 22:04:04 aleph kernel: [<fffffc000032516c>] mmput+0x5c/0x100 Mar 4 22:04:04 aleph kernel: [<fffffc0000329820>] exit_mm+0xc0/0x180 Mar 4 22:04:04 aleph kernel: [<fffffc000032a95c>] do_exit+0x16c/0x950 Mar 4 22:04:04 aleph kernel: [<fffffc000032b184>] do_group_exit+0x44/0xc0 Mar 4 22:04:04 aleph kernel: [<fffffc0000335a9c>] get_signal_to_deliver+0x2fc/0x450 Mar 4 22:04:04 aleph kernel: [<fffffc00003167f4>] do_notify_resume+0xb4/0x570 Mar 4 22:04:04 aleph kernel: [<fffffc00003110cc>] work_pending+0x5c/0x70 Mar 4 22:04:04 aleph kernel: [<fffffc0000333f60>] __sigqueue_alloc+0x40/0xc0 Mar 4 22:04:04 aleph kernel: [<fffffc000038f7a0>] do_ioctl+0x30/0x90 Mar 4 22:04:04 aleph kernel: [<fffffc0000334954>] specific_send_sig_info+0xd4/0x110 Mar 4 22:04:04 aleph kernel: [<fffffc0000334a9c>] force_sig_info+0x8c/0xe0 Mar 4 22:04:04 aleph kernel: [<fffffc0000310bdc>] entMM+0x9c/0xc0 Mar 4 22:04:04 aleph kernel: Mar 4 22:04:04 aleph kernel: Code: a77df1b0 6b5b497f 27ba0039 23bdf664 c3ffffec 00000081 <00000806> 005efcfe Mar 4 22:04:04 aleph kernel: Fixing recursive fault but reboot is needed!

Given that more and more codecs support this sort of thing it's likely that support for digital paths will get implemented at some point. No specific ETA for it, though. Note that if there is no specific reason to use a digital bypass path (such as filtering that is only supported on the digital path or a lack of a suitable analogue path) then it is normally more power efficient to use an analogue bypass path than a digital one.

If there were a direct connection the appropriate thing would just be to declare it (in that particular chip there is actually a digitial mixer in there). Using such a path is not particularly supported by ASoC v1 since it treats ADCs and DACs as sinks and sources only.

[alsa-devel] [PATCH]Should use HDA_OUTPUT instead of HDA_INPUT to mute pin 15 of ALC880
by Jiang zhe 31 Mar '08

31 Mar '08

Hi, To mute the output of Pin widget 15 in ALC880, we should use the HDA_OUTPUT. However, current code looks like : snd_hda_codec_amp_stereo(codec, 0x15, HDA_INPUT, 0, HDA_AMP_MUTE, bits); It may be a misspelling. Best regards! Signed-off-by: Jiang zhe <zhe.jiang(a)intel.com>

This sounds very suspiciously like a difference with playing through the native ALSA interface and the OSS emulaion. Could you and/or Bob confirm that sox is using the OSS emulation and not ALSA natively? I could very well imagine the ALSA OSS emulation being broken on Alpha. I doubt any of teh developers has an Alpha. And if aplay works correctly this seems very likely. "sox" _can_ use ALSA natively as well by the way (see manpage for the version you have installed). > More onerously, my testing eventually ended in a complete system lock up! > I ran play (or was it aplay - sorry can't remember now) Vital if play is using the OSS interface... > and the system locked up.

[alsa-devel] Cannot change volume on Plantronics Audio 910 USB Headset
by cklein＠mpi-sb.mpg.de 29 Mar '08

29 Mar '08

Hi, I recently got a Plantronics .audio 910 USB headset. It is correctly detected by snd-usb-audio and works, but I cannot change the volume of the PCM output or the MIC input. When executing alsamixer -c 1, the volumes seem to be locked and cannot be changed as usual. Unfortunately the microphone volume is at 0, leading to very poor quality of the recorded voice (especially in Skype, which seems to try to compensate the low volume and fails miserably). Does anyone know how to fix this? I found similar reports on the internet for various usb headsets, but no real fix for the situation. I already asked on alsa-users some weeks ago, but did not get any response. I tried the headset on three different PCs, all with the same result. A desktop at work running Fedora 7, a Thinkpad R50p running debian/testing and the 2.6.22 kernel provided in debian/testing. The third one is a Dell precision M65 with debian/unstable. There, I used a vanilla 2.6.24.2 kernel and latest alsa drivers from the mercurial repository when I asked on alsa-users, but in the meantime I upgraded to 2.6.24.3 and hg snapshots from 2008-03-13 06:41 (alsa-driver) and 2008:03:17 05:23 (alsa-kernel), but still got the same behaviour. On all I get some message about "no or invalid class specific endpoint descriptor" in the kernel log (see below). When loading the snd-usb-audio module, dmesg shows the following kernel output (on the M65): usb 2-2: new full speed USB device using uhci_hcd and address 5 usb 2-2: configuration #1 chosen from 1 choice input: Plantronics Plantronics BT Adapter as /devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.3/input/input10 input: USB HID v1.11 Device [Plantronics Plantronics BT Adapter] on usb-0000:00:1d.1-2 usbcore: registered new interface driver usbhid drivers/hid/usbhid/hid-core.c: v2.6:USB HID core driver ALSA /usr/src/kernel-modules/alsa-driver-d20080313_0641-k20080317_0523/usb/usbaudio.c:2787: 5:1:1 : no or invalid class specific endpoint descriptor ALSA /usr/src/kernel-modules/alsa-driver-d20080313_0641-k20080317_0523/usb/usbaudio.c:2787: 5:2:1 : no or invalid class specific endpoint descriptor usbcore: registered new interface driver snd-usb-audio I posted the output of alsa-info.sh and lsusb -v on pastebin (both taken on the M65). alsa-info.sh: http://pastebin.ca/915715 lsusb -v: http://pastebin.ca/915723 -- CU, Christian Klein http://www.garfield.com/comics/comics_archives_strip.html?1979-ga790520 Homepage: http://www.mpi-sb.mpg.de/~cklein

Hello ALSA developers, This problem with the USB sounds card has been reported a while ago, and just been confirmed with latest kernel. ==================================================================== $ cat /proc/asound/cards 0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4 Intel 82801DB-ICH4 with AD1981B at 0xc0000c00, irq 11 1 [U0x4fa0x4201 ]: USB-Audio - USB Device 0x4fa:0x4201 USB Device 0x4fa:0x4201 at usb-0000:00:1d.1-2, full speed If I attempt to play a song using mpg123 or xmms, I get nothing, only maybe click at beggining. I'm using in-kernel OSS emulation. pavel@amd:/mnt/mp3.ptacek/Tanita_Tikaram$ cat /proc/asound/card1/pcm0p/info card: 1 device: 0 subdevice: 0 stream: PLAYBACK id: USB Audio name: USB Audio subname: subdevice #0 class: 0 subclass: 0 subdevices_count: 1 subdevices_avail: 1 pavel@amd:/mnt/mp3.ptacek/Tanita_Tikaram$ I tried unmuting everything using aumix. cat /bin/bash > /dev/dsp1 fails to produce any sound, too. =================================================================== Full bug report is here : http://bugzilla.kernel.org/show_bug.cgi?id=6576 It sure needs some helping hand, maybe someone can take a look into this. Thanks, --Natalie
