As a result of commit d2cd795c4ece ("ALSA: hda - fixup for the bass speaker on Lenovo Carbon X1 7th gen"), the sound output level on my machine, an X1 Carbon 7th gen, was reduced to ~65% of its previous level when playing certain sounds. [1] Internally, this laptop model has three outputs (PCM-OUT1, connection 0x02; PCM-OUT2, connection 0x03; SP-OUT PCM, connection 0x06) which can be routed to two sets of stereo speakers: Front (tweeters, node 0x14) and Bass (woofers, node 0x17, aka Rear in some contexts) and one headphone output (node 0x21). The tweeters are noticeably less powerful than the woofers. [2] Before commit d2cd795c4ece, the bass speakers were connected to SP-OUT PCM. SP-OUT PCM is meant for s/pdif output and does not have volume control. This connection made volume control commonly ineffective (using the Master slider in alsa or pulseaudio apparently had little effect or alternated between mute or max with nothing in between). commit d2cd795c4ece added quirk ALC285_FIXUP_SPEAKER2_TO_DAC1 which resulted in assigning both sets of speakers to PCM-OUT1, bringing the two sets of speakers under one effective volume control but also lowering the output volume noticeably. Fix this by connecting PCM-OUT1 to Front speakers and PCM-OUT2 to Rear speakers. The max output volume is restored to what it was before commit d2cd795c4ece. This is done by setting the connection of node 0x17 to 0x03. However, when we do this, the HDA auto config automatically changes the connection of node 0x21 to 0x02. This output, meant for the front speakers, has some "secret" equalizer which changes the output volume according to the level of what's being played, after some delay[3]. This is undesirable with headphones. Therefore, this patch manually limits the connection of node 0x21 to 0x03. Even though there are three speaker/line outputs (nodes 0x14, 0x17, 0x21), there are only two amps for volume control (nodes 0x02, 0x03). When setting node 0x17 to connection 0x03 and node 0x21 to connection 0x03, amp 0x03 is shared by the Woofer and Headphone outputs. Therefore, they cannot have independent volume control. This patch uses the Speaker control element to regulate nodes 0x02 (acts on tweeters) and 0x03 (acts on woofers and headphones). A virtual control element is created for the Headphone mixer which mirrors the Speaker mixer. These changes are only for volume controls; there are 3 hardware mute controls. The current fixup chain applied to this machine is ALC285_FIXUP_THINKPAD_HEADSET_JACK ALC285_FIXUP_SPEAKER2_TO_DAC1 ALC269_FIXUP_THINKPAD_ACPI ALC269_FIXUP_SKU_IGNORE The fixup added by this patch is an alternative to ALC285_FIXUP_SPEAKER2_TO_DAC1 which must be selected explicitly using the module parameter snd_sof_intel_hda_common.hda_model=alc285-tpx1-dual-speakers when using the new SOF driver architecture, or snd_hda_intel.model=alc285-tpx1-dual-speakers when using the snd_hda_intel driver in legacy mode (see the snd_intel_dspcfg.dsp_driver module parameter). In order to be able to apply ALC285_FIXUP_THINKPAD_HEADSET_JACK without changing current behavior, a new variant of that fixup is introduced. When using the model added by this patch, the fixup chain is: ALC285_FIXUP_TPX1_DUAL_SPEAKERS ALC285_FIXUP_THINKPAD_HEADSET_JACK_ACPI ALC269_FIXUP_THINKPAD_ACPI ALC269_FIXUP_SKU_IGNORE [1] https://gist.github.com/hamidzr/dd81e429dc86f4327ded7a2030e7d7d9#gistcomment-3214171 [2] https://bugzilla.kernel.org/show_bug.cgi?id=207407#c10 [3] https://gist.github.com/hamidzr/dd81e429dc86f4327ded7a2030e7d7d9#gistcomment-3276276 Fixes: d2cd795c4ece ("ALSA: hda - fixup for the bass speaker on Lenovo Carbon X1 7th gen") Link: https://lore.kernel.org/alsa-devel/20200210025249.GA2700@f3/ Cc: Jaroslav Kysela <perex@perex.cz> Cc: Kailang Yang <kailang@realtek.com> Tested-by: Even Brenden <evenbrenden@gmail.com> Tested-by: Vincent Bernat <vincent@bernat.ch> Signed-off-by: Benjamin Poirier <benjamin.poirier@gmail.com> --- This is an updated version of the patchset (now a single patch) to fix the low output volume on the Lenovo ThinkPad X1 Carbon 7th gen. With this patch, the volume output with the Linux driver matches the one with the Windows driver. Volume control is effective and headphone output is unaffected. Multiple users of this machine have reported a low output volume [1] when using a kernel with commit d2cd795c4ece ("ALSA: hda - fixup for the bass speaker on Lenovo Carbon X1 7th gen"). Many have tried these patches or a similar workaround using `hda-verb` and prefer this configuration[2].

Changes: v1 == https://lore.kernel.org/alsa-devel/20200211055651.4405-1-benjamin.poirier@gmail.com/ v2 == https://lore.kernel.org/alsa-devel/20200703080005.8942-1-benjamin.poirier@gmail.com/ * patch 1 Shortened log * patch 2 Change log to replace experimental observations by information from diagram posted on kernel.org bugzilla. Select exactly the desired connection for node 0x17 (bass speakers) instead of reusing alc295_fixup_disable_dac3(). Control node 0x21 (headphones) connection to avoid the volume "wobble" effect described in the log. Include SET_CONNECT_SEL command in fixup since it is not done by the hda core. Rename one control to reflect its new function and to use as a condition in the ucm config. v3 == * Remove patch 1 which was merged separately as commit 9774dc218bb6 ("ALSA: hda/realtek - Fix Lenovo Thinkpad X1 Carbon 7th quirk subdevice id") * Make fixup activation manual using "alc285-tpx1-dual-speakers" model instead of automatic based on codec id. Suggested by Jaroslav. * Control both tweeter and woofer volume from "Speaker Playback Volume" control. This way a separate ucm change is not needed, unlike in v2 of the patchset.
