[alsa-devel] [PATCH v2 1/3] mfd: wm5110: Add registers for custom write sequence triggers
by Charles Keepax 07 Jul '15

07 Jul '15

This register will be needed as part of some additional support for the headphone path on wm5110, so this patch adds the register and sets up its regmap config.

[alsa-devel] g_audio kernel oops on pulling calbe
by Angelo Compagnucci 07 Jul '15

07 Jul '15

Dear Developers, I'm having hard times with g_audio module on a Atmel SAMA5D3. I always obtain a kernel oops in a memcpy inside f_audio_complete function. Honeslty I cannot understand wht's going wrong, cause that memcpy should work. I have a simple ssc sound card whih works as expected when used with aplay or any other audio player software, but when i pull the usb cable this is what I obtain: [ 23.860000] Unable to handle kernel paging request at virtual address 0a080604 [ 23.860000] pgd = c0004000 [ 23.860000] [0a080604] *pgd=00000000 [ 23.860000] Internal error: Oops: 805 [#1] ARM [ 23.860000] Modules linked in: usb_f_uac1 g_audio libcomposite snd_soc_atmel_ssc_dai snd_soc_atmel_pcm_dma [ 23.860000] CPU: 0 PID: 0 Comm: swapper Not tainted 3.19.8+ #81 [ 23.860000] Hardware name: Atmel SAMA5 (Device Tree) [ 23.860000] task: c05327b8 ti: c0528000 task.ti: c0528000 [ 23.860000] PC is at memcpy+0x50/0x330 [ 23.860000] LR is at 0x0 [ 23.860000] pc : [<c01a0430>] lr : [<00000000>] psr: 20090193 [ 23.860000] sp : c0529e5c ip : 00000000 fp : cfb33200 [ 23.860000] r10: 00000001 r9 : 0000bb80 r8 : 00000000 [ 23.860000] r7 : 00000000 r6 : 00000000 r5 : 00000000 r4 : 00000000 [ 23.860000] r3 : 00000000 r2 : 00000020 r1 : cf9f5220 r0 : 0a080604 [ 23.860000] Flags: nzCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment kernel [ 23.860000] Control: 10c53c7d Table: 2fb24059 DAC: 00000015 [ 23.860000] Process swapper (pid: 0, stack limit = 0xc0528230) [ 23.860000] Stack: (0xc0529e5c to 0xc052a000) [ 23.860000] 9e40: cf9f5100 [ 23.860000] 9e60: cfa25868 cf9e7dc0 cfb33080 0a080604 cfb33200 bf0287e0 cfa25858 00000000 [ 23.860000] 9e80: cfa20a10 cfb33200 cfa25858 cfa20a10 cfa20a10 000000c0 00000002 c0284f50 [ 23.860000] 9ea0: c0529ea0 c0529ea0 00000002 00000090 cfa25858 c0286408 0000001c ffffffff [ 23.860000] 9ec0: 7fffffff c054e040 00000000 02000029 cf88cac0 c05544fe c0529ed8 c0529ed8 [ 23.860000] 9ee0: 00000000 cfa23c40 cf802540 00000000 00000000 0000002d cf901dc0 c05544fe [ 23.860000] 9f00: 00000000 c0040b28 c05544fe c0554dc0 cf901dc0 cf802540 00000000 00000000 [ 23.860000] 9f20: cf802200 c051fe18 cfffc480 c0040c18 cf901dc0 c0042e38 0000002d 0000002d [ 23.860000] 9f40: 00000000 c004034c c053aca0 c0040570 c000eec4 60090013 ffffffff c0529f9c [ 23.860000] 9f60: c0554600 c0011b00 00000000 c0536918 00000000 c0017880 c0528000 c05300c4 [ 23.860000] 9f80: c05544fc c05544fc c0554600 c051fe18 cfffc480 00000000 01000000 c0529fb0 [ 23.860000] 9fa0: c000eec0 c000eec4 60090013 ffffffff c0528000 c0039b90 ffffffff c04fac30 [ 23.860000] 9fc0: ffffffff ffffffff c04fa678 00000000 00000000 c051fe18 c05547d4 c0530070 [ 23.860000] 9fe0: c051fe14 c0533860 20004059 410fc051 00000000 20008070 00000000 00000000 [ 23.860000] [<c01a0430>] (memcpy) from [<bf0287e0>] (f_audio_complete+0x11c/0x170 [usb_f_uac1]) [ 23.860000] [<bf0287e0>] (f_audio_complete [usb_f_uac1]) from [<c0284f50>] (request_complete+0x5c/0x80) [ 23.860000] [<c0284f50>] (request_complete) from [<c0286408>] (usba_udc_irq+0x12c/0xc50) [ 23.860000] [<c0286408>] (usba_udc_irq) from [<c0040b28>] (handle_irq_event_percpu+0x78/0x140) [ 23.860000] [<c0040b28>] (handle_irq_event_percpu) from [<c0040c18>] (handle_irq_event+0x28/0x38) [ 23.860000] [<c0040c18>] (handle_irq_event) from [<c0042e38>] (handle_fasteoi_irq+0x9c/0x164) [ 23.860000] [<c0042e38>] (handle_fasteoi_irq) from [<c004034c>] (generic_handle_irq+0x2c/0x3c) [ 23.860000] [<c004034c>] (generic_handle_irq) from [<c0040570>] (__handle_domain_irq+0x54/0xa8) [ 23.860000] [<c0040570>] (__handle_domain_irq) from [<c0011b00>] (__irq_svc+0x40/0x54) [ 23.860000] [<c0011b00>] (__irq_svc) from [<c000eec4>] (arch_cpu_idle+0x38/0x3c) [ 23.860000] [<c000eec4>] (arch_cpu_idle) from [<c0039b90>] (cpu_startup_entry+0xa8/0xf4) [ 23.860000] [<c0039b90>] (cpu_startup_entry) from [<c04fac30>] (start_kernel+0x374/0x380) [ 23.860000] Code: f5d1f05c f5d1f07c e8b151f8 e2522020 (e8a051f8) [ 23.860000] ---[ end trace 6affc0dac289a4ab ]--- [ 23.860000] Kernel panic - not syncing: Fatal exception in interrupt [ 23.860000] ---[ end Kernel panic - not syncing: Fatal exception in interrupt Anyone has a clue about that? -- Profile: http://it.linkedin.com/in/compagnucciangelo

[alsa-devel] [PATCH 1/2] ASoC: fsl_ssi: Add driver suspend and resume to support MEGA Fast
by Zidan Wang 07 Jul '15

07 Jul '15

For i.MX6 SoloX, there is a mode of the SoC to shutdown all power source of modules during system suspend and resume procedure. Thus, SSI needs to save all the values of registers before the system suspend and restore them after the system resume.

[alsa-devel] After kernel upgrade to v ~~> 4.1.0, no audio output unless UNPLUG/RE-PLUGIN of audio jack on card; OK with earlier kernels
by robert.devanna＠nospammail.net 06 Jul '15

06 Jul '15

I run Opensuse 13.2/64. My audio system has been / is ALSA, not PulseAudio. I have installed rpm -qa | grep -i alsa alsa-utils-1.0.29-143.1.x86_64 alsa-plugins-jack-1.0.29-99.1.x86_64 alsa-firmware-1.0.29-33.1.noarch alsa-devel-1.0.29-218.1.x86_64 alsa-plugins-1.0.29-99.1.x86_64 alsa-1.0.29-218.1.x86_64 alsa-oss-1.0.28-51.1.x86_64 alsa-docs-1.0.29-218.1.noarch It's run fine for ages. In the past week -- after a bunch of zypper (distro packages) upgrades, and no I don't know which one specifically -- I now have an audio problem. When I boot my machine there's no audio output. Every alsa/sound diagnostic I ran said everything's OK. Took me awhile to figure out that simply UNPLUGGING the audio jack from the mobo socket, then replugging it in fixes the audio -- immediately. Chatting in #irc, suggestion was to check kernel version dependency. I'm currently on latest stable kernel 4.1.X. uname -rm 4.1.1-1.ga46abf6-desktop x86_64 I am absolutely sure that this was NOT a problem in the 4.0.X kernel branch. I am pretty-darn-sure that this was NOT a problem in earlier 4.1.X branch. Unfortunately, I only had access to 4.1.1-1.1.ga46abf6 4.1.0-3.g5ee367d and 3.16.7-21.1.x86_64 no longer any earlier 4.1.X or 4.0.X kernels. Testing each of those 4.1.1-1.1.ga46abf6 --> FAILs 4.1.0-3.g5ee367d --> FAILs 3.16.7-21.1.x86_64 --> WORKs so at least from 3.16.7 -> 4.1.0 there's a kernel dependency. Again, I'm pretty certain that this was NOT a problem with earlier 4.1.X and 4.0.X kernels; just can't prove it. As instructed in IRC, I DL'd and exec'd the 'alsa-info.sh' script. I ran the script in 2 cases: [1] boot to console, kernel 4.1.1-1.1.ga46abf6, no audio output [2] boot to console, kernel 4.1.1-1.1.ga46abf6, unplug & replug, OK audio output First, the DIFF between the two shows there IS a change on UNPLUG/REPLUG of the jack, DIFF: ------------------------------------------ --- alsa-info.txt.BEFORE 2015-07-05 12:32:44.973554471 -0700 +++ alsa-info.txt.AFTER 2015-07-05 12:34:01.935900433 -0700 @@ -3,7 +3,7 @@ !!ALSA Information Script v 0.4.64 !!################################ -!!Script ran on: Sun Jul 5 19:32:43 UTC 2015 +!!Script ran on: Sun Jul 5 19:34:00 UTC 2015 !!Linux Distribution @@ -332,7 +332,7 @@ Pin-ctls: 0x40: OUT Unsolicited: tag=01, enabled=1 Power states: D0 D1 D2 D3 - Power: setting=D3, actual=D3 + Power: setting=D0, actual=D0 Connection: 1 0x16 Node 0x1d [Pin Complex] wcaps 0x40058d: Stereo Amp-Out @@ -602,7 +602,7 @@ crw-rw---- 1 root audio 116, 6 Jul 5 12:31 /dev/snd/hwC0D0 crw-rw---- 1 root audio 116, 10 Jul 5 12:31 /dev/snd/hwC2D0 crw-rw---- 1 root audio 116, 4 Jul 5 12:31 /dev/snd/pcmC0D0c -crw-rw---- 1 root audio 116, 3 Jul 5 12:32 /dev/snd/pcmC0D0p +crw-rw---- 1 root audio 116, 3 Jul 5 12:33 /dev/snd/pcmC0D0p crw-rw---- 1 root audio 116, 5 Jul 5 12:31 /dev/snd/pcmC0D3p crw-rw---- 1 root audio 116, 12 Jul 5 12:31 /dev/snd/pcmC1D0c crw-rw---- 1 root audio 116, 8 Jul 5 12:31 /dev/snd/pcmC2D3p ------------------------------------------ Since the output's too big for the list, apparently, I pastebin'd the full script output [1] -> http://pastebin.com/jUyTRrFG [2] -> http://pastebin.com/4V8YCguV - Rob
